[Freeipa-users] IPA - AD performance issue

[Alexander Frolushkin]

Hello!
We have a very large AD and IPA trusts with it.
Every time user tries to login to client server, on corresponding IPA server we have a tons of messages like this:

This process seems to take significant time, and sometime ssh client even breaks connection with timeout.

Not sure is this a some kind of arch problem, or we have wrong settings somewhere.
Just to mention, usually, this sid's is a indirect membership groups, local and does not affecting's any access rules for this user.

WBR,
