Problem with ldapsync after server crash in OpenLDAP server

[skallen]

Hi all,

I have problems after having to move our openLDAP server to a new server, we did restore an ldif backup and after this we are not able to modify accounts.
The error messages is like:
Failed to locate or retrieve information in LDAP for id 7cd537d6-f228-102a-98f9-efbc7a07903a

I realize that the id must have been changed on the openLDAP server, but is there any way to fix this without having to backup the users mailboxes and delete the users?

Looks like the unique id for your users has changed in the new LDAP server. My first instinct tells me that you will have to run omldapsync with the -L flag to reload the Scalix directory. You'd then have to accept (either -A or -P) any errors.

Your other choice is to obtain all the new unique ids and come up with a script which will run an ommodent for each affected Scalix directory entry and change the unique id to match that of the LDAP server.

Hope this helps.

Thank you for the reply.

But it did not help, the omGlobalUniqueId did no change in scalix.

And when i run ommodent it looks like i can't change the omGlobalUniqueId...

[root@scalix ~]# ommodent -e "S=Olsson/G=Mikael/OU1=se-ka-sr020/OU2=se-ka/CN=Mikael Olsson" -n omGlobalUniqueId=79f964e2-f228-102a-9742-efbc7a07903a
omGlobalUniqueId=79f964e2-f228-102a-9742-efbc7a07903a
[OM 16073] Unknown attribute specified.

Attribute : omGlobalUniqueId

The solution that works so far is:
backup a mailbox
delete the user
remove the scalixUserClass for the user in OpenLDAP
run omldapsync
delete the user in scalix
add the scalixUserClass in OpenLDAP
run omldapsync
restore the mailbox

But this is a very slow process and might not even work for some users with big mailboxes (> 2GB), so i really need some way to modify the omGlobalUniqueId in scalix.

I found out that i did it wrong, it should have been:

ommodent -e "S=Olsson/G=Mikael/OU1=se-ka-sr020/OU2=se-ka/CN=Mikael Olsson" -n GLOBAL-UNIQUE-ID=79f964e2-f228-102a-9742-efbc7a07903a
Now i can fix the problem.

Thanks for the help anyway
