[Freeipa-users] adding user to a group failed

[Martin (Lists)]

Hallo

recently I tried to add a user to one of my groups, but this always
failed with the error message: This entry already exists.

Of course does this entry (user) exists, but not in this group. and it
is not added. I tried to add this from web interface and command line
with the same result.

I use freeipa version 4.1.4 on fedora 22

Anyone with a tip?

Regards
Martin
