Please elaborate on "quite a few groups" - actually this is a well

I was afraid you might have permissions on "too many objects" or
that the account is a member of too many groups.
However, being a member of too many groups should have caused the
search to be slow/hang as well.
I don't have an exact count, but I think its along the order of
magnitude of 300-400.
Hi,
I gave an incorrect explanation before (I thought about it and understood where
my error lies ).
If I add a user using engine-manage-domains and do not provide -addPermissions, I
will still be able to login to the system using admin@internal, and perform search
for users & groups.
This means I do not need to have permissions for the user I added for that domain to
perform search so the "permissions" check is of course not performed at search!
The number of groups is important in login - oVirt will try to calculate all
the permissions of the users, and this is based on the permission the user have
directly on an object, or that its group has.
If the user is a member of 300 groups, oVirt tries to get information for all
that groups.
THis is why login hands, but search does not hang.
I guess I don't understand why ovirt needs to do that. You should be
able to get the list of groups a user is a member which I thought was
sufficient for most apps to determine authorization.
I know we use AD authentication for a lot of things and i've never hit
this before.
Changing the AD config isn't something I can do so it sounds like there
is no workaround and i'll just have to live with the local
authentication. Or pehaps I can stick some ldap server in front of AD that
