Hi everybody,
I've got a Problem with my DTR.
Recently we've set up the new CE 7.2 System.
The DTR has run until about 3 hours ago.
I don't know what I've done that this error occurs, but I'm nearly shure that I haven't done anything that depends on the dtr.
I went through the set up wizzard of "Connect Design Time for Visual Composer with NWDI" again, but nothing changed.
Can you please help me with this issue?!
Thank you and best regards
julian

Hello Julian
This is a known problem.
Cause
- A user may have been added to a group in another ldap tree with a name, that is already existing.
- When DTR retrieves the group from UME, we get 2 similar group names, but the groups may be different.
- DTR cannot handle this and throws "Internal Server error"
Resolution
If you change parameter "ume.ldap.unigue_grup_attribute" to 'uid', DTR doesn't use the groupname,
but the group-uid, therefore the group is unique.
1. open Visual Administrator
2. choose Services
3. choose UME Provider
4. Reset "ume.ldap.unigue_grup_attribute" with 'uid'
5. restart the system
Thanks
Kenny.
