Activating Enable SSL connection to Active Directory from the UI has no effect on the SSL activation for LDAP user import

[AndreeaChi]

Hi,

Active Directory used: 1.14.1 (also tested with 1.15)

While trying to use the Enable SSL connection to Active Directory server option from the UI configuration, it was noticed that it did not actually enable the SSL connection fully.

To be more exact, this is what it happened:

• The login was possible and user creation happened upon first login (so it could look that the SSL connection is working)
• but importing users did not work.

Settings done on the AD UI Configuration:

• Enable SSL connection to Active Directory server option set to Yes
• PATH TO SSL KEYSTORE and SSL SECURE PROVIDER field not completed

Result:

• Login and user creation worked
• the import does not work.

If completing PATH TO SSL KEYSTORE and SSL SECURE PROVIDER fields, while also Enable SSL connection to Active Directory server option set to Yes, nothing works anymore: login, user creation, import of users.

Current workaround:

• After setting in the xwiki.cfg xwiki.authentication.ldap.ssl=1 , the user import worked along with the login and user creation. Note that the PATH TO SSL KEYSTORE and SSL SECURE PROVIDER fields need to be left empty on the AD UI config side so that LDAPS login, user creation upon login and import can work.

• The login was possible and user creation happened upon first login (so it could look that the SSL connection is working) but importing users did not work.
• but importing users did not work.

I think this means the SSL connection is in fact working but there is an issue with the user import feature, which is not implemented directly in the Active Directory Application but in a separate application, LDAP User Import Application, that is installed as a dependency. The fact that the features implemented directly in Active Directory Application (login and user creation) work when enabling SSL from the administration section, and the features implemented in LDAP User Import Application don't (user import), is a strong indicator that the LDAP User Import Application doesn't obey the SSL configuration from the Active Directory Application.

I checked the code quickly and indeed:

• Active Directory Application takes into account the SSL setting when building the XWikiLDAPConfig
• while the LDAP User Import Application does not; basically the LDAP User Import Application relies on the SSL configuration coming from the xwiki.cfg instead of using the config coming from the Active Directory administration section

Fixing this may not be that easy, because LDAP User Import Application is a dependency of the Active Directory Application so it doesn't know about Active Directory Application (otherwise we would have a cyclic dependency). So the LDAP User Import Application can't use directly the configuration xclass / xobject provided by the Active Directory Application. Basically the Active Directory Application should extend / overwrite the LDAP configuration in such a way that any code using LDAP (e.g. the LDAP User Import Application) is using the same configuration.

I've encountered this issue while testing on XWiki 14.10.10 with Active Directory Authenticator 1.16.2, Chrome 116.

Click on Import user from the Users section from the XWiki Administration, next to "Create User" button (in the main wiki) then search for a user from AD ex. "user"

I ran into this issue as well on an on premise installation. The AD connection was successful however the LDAP user import failed, but with a different error:

org.apache.velocity.exception.MethodInvocationException: Invocation of method 'getUsers' in

As mentioned above, setting xwiki.authentication.ldap.ssl=1 in xwiki.cfg and restarting XWiki fixed the issue. Maybe we could give this issue a title like "Activating Enable SSL connection to Active Directory from the UI has no effect on the SSL activation for LDAP user import"? And label it as "Type:Improvement"?

[ane-gabriela]

Issue reproducing on XWiki 15.10.8 with Active Directory Application 1.16.14, Windows 11, Chrome 125

1. The Test connection worked only with the steps also stated above

   • setting Enable SSL connection to Active Directory server option set to Yes (ACTIVE DIRECTORY SERVER PORT 636)
   • leave the PATH TO SSL KEYSTORE and SSL SECURE PROVIDER field not completed
   • adding in xwiki.cfg `#-# SSL connection to LDAP server

     -# - 0: normal

     -# - 1: SSL

     -# The default is 0

     xwiki.authentication.ldap.ssl=1`

2. The user import didn't work
