PAM Authentication Failure With FTP And Apache Suexec
Jun 18, 2007
i am trying to setup a VPS with:
Apache Suexec, so that each VHosts runs under there own username
FTP for each of the vhosts.
I have made a username aplushost and FTP works fine when i login, however when i try and get Suexec to work it shows a 403 permision dined, even know the whole directroy path is with correct permsions.
"/home/aplushost/www"
However if i chown the directroy "aplushost" to apaches username , currently "nobody" i have tried with "apache" and many others the page is displayed correctly.
The weird thing is that the www directroy can still be set to the aplushost username and files work inside.
However due to changing the privalages of the folder aplushost ftp now fails to login due to the folder not being owned by the ftp user "aplushost".
So im stuck between only having one item working at a time.
i have put some content of my config files.
----------httpd.conf vhosts------------------
<VirtualHost 87.117.196.247>
DocumentRoot "/home/aplushost/www"
ServerName aplushost.co.uk
SuexecUserGroup aplushost aplushost
<Directory "/home/aplushost/www">
allow from all
Options +Indexes
</Directory>
</VirtualHost>
---------------passwd file----------------
aplushost:x:500:99::/home/aplushost/www:/sbin/nologin
(Have tried with many different shells, no difference, also tried with home directroy as just /home/aplushost)

I have a new Plesk 11.0.9. #34 server with Centos 6.3 64bit.
I made a few changes in order to be PCI Compliant.
I created a domain and try to send email with no luck.
----------Maillog------------
Jan 24 16:01:28 server7 pop3d-ssl: Connection, ip=[::ffff:X.X.X.X]
Jan 24 16:01:34 server7 pop3d-ssl: IMAP connect from @ [::ffff:X.X.X.X]ERR: LOGIN FAILED, ip=[::ffff:X.X.X.X]

Jan 24 16:01:48 server7 pop3d-ssl: Connection, ip=[::ffff:X.X.X.X]
[Code] ....
As you can see from the logs, the pop/imap connection is successful. I login to webmail with the username/password successfully. I can't send from Outlook/thunderbird etc.
Tried to rebuild emails with /usr/local/psa/admin/sbin/mchk --with-spam but no luck.

First uninstall your existing PHP.
Install httpd-devel
Second compile a new PHP with support of cgi/fcgi:
Code:
./configure --prefix=/usr/local/php-fcgi --enable-fastcgi --enable-memory-limit --with-mysql=shared,/usr --enable-discard-path --enable-force-cgi-redirect --with-imap=shared,/usr --with-gd=shared,/usr --with-libxml=shared,/usr --with-mbstring=shared --with-freetype-dir=/usr --with-jpeg-dir=/usr --with-png-dir=/usr --with-zlib-dir=/usr --with-kerberos --with-imap-ssl
make
make install
To solve the errors during configure problems take a look at this:
[url]
Next you'll need to download/install fcgid:
Code:
wget http://www.fastcgi.com/dist/fcgi-2.4.1-SNAP-0311112127.tar.gz
tar xfvz fcgi-2.4.1-SNAP-0311112127.tar.gz
cd fcgi-2.4.1-SNAP-0311112127
./configure
make
make install
Next you'll need to compile/install mod_fastcgi for Apache 2.2.2:
Code:
wget [url]
tar xfvz mod_fastcgi-SNAP-0404142202.tar.gz
cd fcgi-2.4.1-SNAP-0311112127
Now we need to apply a patch so mod_fastcgi compiles with Apache 2.2. Put the following into a file:
Code:
diff -ruN mod_fastcgi-2.4.2/Makefile.AP2 mod_fastcgi-2.4.2.for22/Makefile.AP2

Why this error might have started to appear? I am fairly new to apache and was trying to harden it up.
I am use CentOS:
Server version: Apache/2.2.25 (Unix)
Server built: Oct 7 2013 17:21:18
Cpanel::Easy::Apache v3.22.14 rev9999
I was trying to add a group to control access to specific groups to enforce some security:
chown -R root:root /usr/local/apache/bin
chmod -R 770 /usr/local/apache/bin
chown -R root:root /usr/local/apache/conf
chmod -R 770 /usr/local/apache/conf
groupadd apacheadmin
groupadd apache
useradd -d /usr/local/apache/htdocs -g apache -s /bin/false apache
I think this is a permission issue.

I have a machine at home running the UniformServer wamp package on Win2K3 Standard server and I'm hosting a simple family picture gallery using Gallery 2.3. I put the gallery in a subdirectory of root so I could have a public homepage and a gallery that is password protected. I did this using .htaccess and .htpasswd.
My issue is when I browse to mydomain.com and click the link to the gallery [url], the password box pops up, and when I enter the appropriate credentials, the domain name reverts to the IP and another password box pops up. If I log in a second time, I'm fine. If I cancel that second login, it still lets me in, but prompts me to login that second time for every click going forward until I authenticate.

I have a couple of directories on my server that require authentication (MySQL DBD and AuthUserFile). Both work fine with SSL off. When I use SSL on directories without authentication that also works fine. However, when I put the 2 together, authentication is by-passed. I cannot seem to get the configuration right to do both. Here is my VH conf file (sanitized):
Code:

I'd appreciate if you can point out some links, or if anyone is willing to help me for a fee, we can talk about it.
I have a web application called MyApp
- Each MyApp user has 5gb hosting, and a web interface to manage their files.
- Therefore MyApp user gets a user account on linux machine and has access to only one directory /repo/usr/<user_id> and nowhere else. (suexec?)
- If that MyApp user creates a subdomain from any folder inside his home folder (he can do that using web interface), that folder is readable by www-data user not writable.
- That myapp user is able to mount/unmount his own ftp drives using curlftpfs.
- In short, users can only mess with their own files and they have no access nor rights to any other file that is outside of their home dir.
In short, this is a kind of hosting company server setup. Right now, we will have to manage all this from -only- one powerful server.

I have some questions about the LDAP authentication module.I have a LDAP authentication with this config:
<AuthnProviderAlias ldap ldap-account>
AuthLDAPBindDN "CN=directory search,OU=Service-User,DC=company,DC=ch"
AuthLDAPBindPassword "xxxxx"
AuthLDAPURL "ldap://ldap.company.ch/ou=Users,dc=company,dc=ch?sAMAccountName?sub?(objectClass=*)"
</AuthnProviderAlias>
If a User logs in with username only, all works correct. If a user use the DomainUsername format, the login is rejected with "user not found".Should it not work with both login styles ? Or is there a option to reformat or rewrite the username before authentication without the "Domain part ?

Is this simple authentication or SASL Digest MD5, ..)?
we are able to specify only the 'authbasicprovider ldap' ldap url, bind username and password in the apache httpd configuration file.
Can LDAP SASL (Digest MD5, GSSAPI,…) mechanism be specified in the Apache configuration during authentication?
If so, how to specify the LDAP SASL mechanism?

I was wondering if there's a simple way to implement some kind of authencation bruteforce protection in apache for windows? Right now my authentication never stops asking if user inputs the wrong credentials, this makes me think i'm vounrable for bruteforce attacks which could eventually get through if given the time.

I have to create a structure in which there is a client, a server and an authentication authority.
The authentication authority verifies the identity of both the client and server before they can communicate, so that the client can access the content offered by the server. Everything must be made using HTTP with SSL (HTTPS).
For now I have installed xampp on my pc with ubuntu, I performed the initial configuration and was able to view a test page locally hosted by entering the URL of the virtual server "www.server.it" (added to the configuration of apache2).

In web application we are facing high vulnerability issue based on the session validation.
We can download the files from the server whenever we are passing the link even without login. The links are directly hit into the server and download the files any type of files extension such as .txt, .xml, .zip and so on.
Need the solution for this issue: How will we resolve the issue using validate the session in apache side?
Scenario as below:
When user manually passing the request if user logged they should access the files
When user manually passing the request if user is not login they shouldn't access the files
Here both the scenarios they can access the files but we want to restrict when the request is coming to apache without login.
EX: [URL] ....
When i tried above link I can able to view the file in browser. Even able to download all different fies extension which are having in the under tomcat webapps dir.
How we can restrict this in apache code or any other files in apache side or is there any way to validate the request is logged one or not?.

I am setting up apache 2.4 as a service locally through localhost on a windows 2008 R2 standard server. I have set up SSL listening on port 443 and works correctly, however I am having trouble figuring out how to get apache to authenticate my CAC card.
I have downloaded the DOD certs and put them into various types of files including pem, base 64, der etc and I have yet to figure out a way to get the client certificates validated.
I have left out the information about the SSLCertificateChainFile, SSLCACertificateFile and SSLCARevocationPath as I am sure this must be where my problem is.
Is it possible to get this done through localhost. Here is the error I am getting in the error log.

I am running apache currently on my QNAP server, and have enabled webserver and LDAP. We have set up users on LDAP. I have created a landing page for access from the internet. I want to configure Apache to authenticate the users using LDAP before granting access to the landing directory.
I have started this with the apache configuration below: My apache config file -
Code:
LogLevel debug
CustomLog "logs/access_log" combined
ErrorLog "logs/error_log"
LoadModule ldap_module modules/mod_ldap.so
LoadModule authnz_ldap_module modules/mod_authnz_ldap.so
ServerName MyServer
LDAPTrustedMode NONE
LDAPVerifyServerCert Off
[Code] ....
When I access my page, I get the authentication prompt. But when I enter my LDAP login and password, I get thrown out of the system with the error:
Internal Server Error
The server encountered an internal error or misconfiguration and was unable to complete your request.
Please contact the server administrator, admin@NAS and inform them of the time the error occurred, and anything you might have done that may have caused the error.
More information about this error may be available in the server error log.
Looks like my apache configuration is a problem as I am able access my LDAP and everything with LDAP seems to be working fine except Apache configuration to authenticate against LDAP.

We have a website running on Apache ver 2.2.3.
A couple of directories on the website need authentication against LDAP. The setup has been working for many years and all of a sudden is giving some issues.
The page asks for authentication and once login details are entered, either it throws an error "Page has moved" or "Please refresh your browser or reload the page".
As far as I am aware no configuration has been changed for LDAP or for Apache. The website runs on Windows Server 2003.
I am very much new to Apache and cannot seem to find any errors logged.

Im having a problem where local authentication will not work when when the configured LDAP server is unavailble. When the ldap server is online I can authenticate fine against ldap and local file. However, when the ldap server is offline, I cannot authenticate with the user1 account. The browser just sits at a blank screen.
Ive searched a lot on this and found many examples, all very similar to my config below, but I still cannot failback authentication to local file when ldap is unavailable. Im running Apache/2.2.10. I have also tested this on 2.2.16 with the same results.

I have several applications that use authentication and expect REMOTE_USER to be set by Apache for authentication/authorization.
I am putting a reverse proxy, with shibboleth in front of these applications, on a separate server.
Currently, REMOTE_USER is not sent. I have tried a few things, and I am currently sending it inside another header, but I have some applications that are closed sources and this will not work.
Is this possible to do? I am running this with Apache 2.4.7, I believe, on the Windows platform.

I have a class project that we are working on where we have to configure and implement an Apache server with ssl using ldap for authentication. I have documentation of literally everything I have done in the configuration. Everything seems to be fine with the config that I can tell. The client gets a prompt for username and password when they access the server ip address. However, once the correct username and password are entered, then the client receives a 500 internal server error message instead of the webpage: "Internal Server Error...The server encountered an internal error or misconfiguration and was unable to complete your request.

I installed lsws without apache conf file(httpd.conf). Then I created a new virtual host in "suEXEC" Template. I added a new user via SSH and made home dir for him and chowned his home dir + all his files to hisusername:hisusername. His home dir(/home/user/) is chmoded to 755 and his /public_html to 711. It worked fine but after that I installed phpbb3 forum and when I tried to chmod config.php to 600 I got an error on the forum:
Fatal error: require() [function.require]: Failed opening required './config.php' (include_path='.:/usr/local/lib/php') in /home/username/public_html/common.php on line 127
When I was using lsws with apache conf file and I had configured suEXEC + suPHP for apache I was able to chmod config file to 600 and it worked fine. I have no idea what could be the problem now.
It works fine when I chmod config.php to 755 but for security reasons I would need a way to configure it to 600.
