AD / LDAP integration

Hello everybody,

I Have a problem with the nextcloud version 12.04 on the AD / LDAP integration part, can you help me?

I get groups via the AD for some it works without problems but others charge indefinitely.

I have this message for :
OC\User\NoUserException: 0C36738F-DAD8-4DE1-B258-8E20FDDF46BA is not a valid user anymore

[internal function] OCA\User_LDAP\User_LDAP->getHome('0C36738F-DAD8-4...')

Nextcloud : 12.04
PHP : PHP 7.1.12
Mysql : 5.5.58

Thanks a lot,

Yeah. I have that problem too from time to time. LDAP is not as mature as it should be. For example group membeships are not recognized all the time. No idea how to solve this at the moment.

Maybe this bug is related to my problem: https://github.com/nextcloud/server/issues/7606
