Setup of ldap-ad in alfresco

[enr]

Dear all,

I have many problems on setting up a working ldap-ad configuration in alfresco. I already tried several solutions proposed in other posts but they didn't work at all.
Here my  configuration:

repository.properties

authentication.chain=ldap-ad1:ldap-ad
‍‍‍

ldap-ad-authentication.properties

ldap.authentication.active=true
ldap.authentication.allowGuestLogin=false
ldap.authentication.userNameFormat=%s@example.org
ldap.authentication.java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory
ldap.authentication.java.naming.provider.url=ldap://xxx.xxx.xxx.xxx
ldap.authentication.java.naming.security.authentication=simple
ldap.authentication.escapeCommasInBind=false
ldap.authentication.escapeCommasInUid=false
ldap.synchronization.active=true
ldap.synchronization.java.naming.security.principal=username@example.org
ldap.synchronization.java.naming.security.credentials=mypassword
ldap.synchronization.queryBatchSize=1000
ldap.synchronization.groupQuery=(objectclass\=group)
…
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

This is the error tomcat report on catalina.out:

Please, could anyone tell me what it's wrong? It seems to be a credential problem but I tried to connect with an LDAP browser with the same credentials and it works.

Thank you very much.

Judging from the logfile LDAP is not (yet) your problem: Alfresco says it cant start its builtin FTP-Server. So you should either disable this feature (i'd do this anyway unless you really have a good use case for FTP); or check why FTP cant start (Running Alfresco as non-root on Unix? Other FTPD running? Possibly Firewall on Windoze?)

Thank you for your answer,
I posted the wrong part of the log file, this one is the correct one related to LDAP service.

I don't think the ftp problem is related to ldap, or I am wrong?
For now I am only interested to setup a working connection between my active directory and alfresco.
I am running alfresco under unix.

Thank you

Hello,

As the log say "LDAP authentication failed", it seems that Alfresco could not log to the ldap server.
You maybe have to change the following value with a user which could authenticate to the server:

ldap.synchronization.java.naming.security.principal=username@example.org
ldap.synchronization.java.naming.security.credentials=mypassword
‍‍‍‍

Hope this helps.

Thank you Alain,
this was exactly the solution to my problem. Unfortunately I have another problem related to the fact that I am not able to log in Alfresco with user name and password stored in my active directory.
I am trying to setup only the authentication through active directory in alfresco, I tried a lot of different configuration but I always had problems.
This is my ldap-ad-authentication.properties

ldap.authentication.active=true
ldap.authentication.allowGuestLogin=true
ldap.authentication.userNameFormat=%s@domain
ldap.authentication.java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory
ldap.authentication.java.naming.provider.url=ldap://xxx.xx.x.x:389
ldap.authentication.java.naming.security.authentication=simple
ldap.authentication.escapeCommasInBind=false
ldap.authentication.escapeCommasInUid=false
ldap.authentication.defaultAdministratorUserNames=Administrator
ldap.synchronization.active=false
ldap.synchronization.java.naming.security.principal=user@domain
ldap.synchronization.java.naming.security.credentials=password

Hello,

… active directory …

As we have no Windows server and no active directory, I cannot help you with authentication through an AD.

But are you sure that you have to modify the xml files ?

I thought that from 3.2, you only have to add a subsystem and then change property files.

Greetings,
Alain

[enr]

Hi,
thank you very much for your replies. I think that the problem resides in the beans defined in the common-ldap-context.xml. I didn't change anything of the xml file, I only set up the minimum configuration on ldap-ad-authentication.properties file (I read in other posts related to this topic how to do it).
I currently installed the alfresco version 3.2r2 but I didn't find any useful help on this topic.
I don't know if it's better to change the common-ldap-context.xml or working on the ldap-ad-authentication.properties
However I am quite sure the problems resides in the beans definition of the common-ldap-contenxt.xml

Greetings,
Enrico

[enr]

Well,
I think to be near to the solution. I find out that xml files are not necessary (as Alain suggested). Now the log file returns the following information:

14:20:13,601  INFO  [management.subsystems.ChildApplicationContextFactory] Startup of 'Authentication' subsystem, ID: [Authentication, managed, ldap-ad1] complete
‍‍‍

It seems that my configuration is correct but I am still unable to access with my active directory credentials.
With softerra I used the following information:

base=OU=TEMPORARY,OU=Users,OU=Domain,DC=DOMAIN,DC=DOMAIN2,DC=ORG
URL=ldap://172.19.6.1:389/OU=TEMPORARY,OU=Users,OU=Domain,DC=DOMAIN,DC=DOMAIN2,DC=ORG??base?(objectClass=*)
userPrincipalName = name@xxx.org
‍‍‍‍‍

I set up my ldap-ad-authentication.properties in the following way:

ldap.authentication.active=true
ldap.authentication.allowGuestLogin=true
ldap.authentication.userNameFormat=%s@xxx.ORG,OU=TEMPORARY,OU=Users,OU=Domain,DC=DOMAIN,DC=DOMAIN2,DC=ORG
ldap.authentication.java.naming.factory.initial=com.sun.jndi.ldap.LdapCtxFactory
ldap.authentication.java.naming.provider.url=ldap://xxx.xxx.xxx.xxx:389
ldap.authentication.java.naming.security.authentication=simple
ldap.authentication.escapeCommasInBind=false
ldap.authentication.escapeCommasInUid=false
ldap.authentication.defaultAdministratorUserNames=Administrator
ldap.synchronization.active=false
ldap.synchronization.java.naming.security.principal=user@domain
ldap.synchronization.java.naming.security.credentials=mypassword
ldap.synchronization.queryBatchSize=1000
‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍

I am sure I am missing something very simple on the configuration, like the base setup or something similar.
Anyone can help please?

Thank you,
Enrico

[enr]

Well, finally I found the correct configuration for ldap-ad authentication.

The problem now reside on the override of the configuration file regarding ldap-ad files. I read in other posts that this problem was a bug which should be solved.
I am using the 3.2r2 version.

I put the alfresco-global.properties file in:
/srv/www/tomcat55/base/shared/classes

The ldap-ad-authentication-context.xml  ldap-ad-authentication.properties in:
/srv/www/tomcat55/base/shared/classes/alfresco/extension/subsystems/Authentication/ldap-ad/ldap-ad1

If I rename the files in /srv/www/tomcat55/base/webapps/alfresco/WEB-INF/classes/alfresco/subsystems/Authentication/ldap-ad all works in the right way, otherwise, if i didn't rename the files, the files in  /srv/www/tomcat55/base/webapps/alfresco/WEB-INF/classes/alfresco/subsystems/Authentication/ldap-ad have priority in the files I created to override the configuration.

Any help please?

Thank you,
Enrico
