AdminSDHolder protects a non high priviliged user

Hi @ all,

i ' ve got a Problem with a User that is protected by AdminSDHolder, but the User is not in a high privileged group.

I have seen, that the adminCount was set to 1 so i set it 0. Maybe the user was in the past a Admin. Afterwards i activate the inheritable permission ...

But after 60 minutes later the AdminSDHolder hat reverted the settings.

How can i determine why the User is protected by AdminSDHolder?

Thank's

Kind regards

Adrian
