SSSD keeps retrieving LDAP groups while online, degrading performance (no matter what settings I try)
by Robert Wagensveld
Hi all,
We've been using SSSD for a while successfully in our Kerberos over LDAP enterprise environment. However, our SSSD online query time, especially over VPN, is very poor, usually each login request or sudo requests takes about 1 minute. There does not seem to be a way around it, not even forcing SSSD to use the cache for a while even when online again. entry_cache_timeout does not help. Is there anything I'm missing? Some configuration options I do not know about yet?

Samba filesharing, ssh and sssd
by Harald 11
Hello!
I am using sssd 2.4 with Debian 11.
I try to setup a samba server within a samba ads domain. I did several approches, sssd with ad and ldap configuration and samba with ad, sss and nss backend.
Basic setup with sssd went good, login via ssh works. UID and GID are well too But I do not get samba run well. Either my user can't access server and see shares, nor I can access shares but UID and GID are wrong.
Which way is best to get ssh and samba running with sssd?
