Customer User Backend, Auth Backend and Customer Users

8 Nov 2004

      Hi all,

First I apologize for my poor english !

I currently work on multiple customer id / Customer User <-> Groups.

I use an LDAP backend for authenticating my users and LDAP backend to
extract information about us.

In the Auth backend I use an LDAP group to know if someone is an
authorized customer/agent. I Use the LDAP's data backend to mapping
LDAP data to the OTRS user who are authenticated. For this part all is
very good ! (OTRS is the first product I see who really separate Auth
backend and User's data backend !)

The problem is:
    When I open ticket, I can't see it (I think the multiple Ids don't
work for my configuration. I have made no configuration in Customer
User <-> group. I can see the CustomerIds in the agent interface and
it is correctly set.
    When click on Customer User <-> group or Customer User, OTRS try
to list all LDAP user instead of list only users who belong to the
LDAP's group in Auth backend config.
I think it's because OTRS use the User's data backend to make this list.
In the User's data backend config there is no way to limit searches by
adding an LDAP group. There is only an AlwaysFilter. So there is an
undocumented option for this backend to restrict data backend with an
LDAP group ?

Thanks to the help ;)

Regards,

     Yann

ps: 
I use OTRS 1.3.2
Some extract of my config:
