Hi All!
Work very well with sssd+ad provider, but sudo su - very slow working when running first time(running again <1sec), user1@host$ sudo su - ( slow ~ 8-15 sec).
user1 domain user - member of many groups (+300) in Active Directory.
/etc/sssd/sssd.conf:
[domain/default] cache_credentials = true ignore_group_members = true
[domain/domain.local] debug_level = 6 id_provider = ad ad_server = msa-dc13. domain.local, msk-dc11. domain.local ad_domain = domain.local ad_hostname = msa-mailsys1.domain.local override_homedir = /home/%u override_shell = /bin/bash ignore_group_members = true
# FILTER access_provider = simple simple_allow_groups = ROL-Linux-Admin
[sssd] services = nss, pam, sudo cache_credentials = true config_file_version = 2 domains = domain.local [nss] debug_level= 6 [pam]
[sudo] #debug_level = 9
In /var/log/sssd/sssd_nss.log more requesting to domain,when run sudo first time. Whether it is possible to cache operations with sudo or or some other way to get around there is the problem?

Yeah, I guess the groups are not cached the first time around.
What SSSD versions are you running?
Can you attach the nss and domain log so we can see what exactly is being requested? You're already using ignore_group_members which would be my guess..
If you're running a recent enough version, maybe the background refresh would be useful..
btw feel free to drop the [domain/default] section, it's not used anywhere..

Hi :)

refresh_expired_interval?

Yes, but you're running RHEL/CentOS 6.6, that's not recent enough, sorry. The background refresh will be released in 6.7 (which is supposed to be out Any Day Now)
Ok, i have this conf in EL7 envirement. sssd -1.12.2-58.el7.x86_64. In el7 sssd can work something out?
entry_cache_ sudo _timeout is useful or do i need refresh_expired_interval?

No, sorry, also too old :-(
Upstream only gained this option in 1.12.5 (in 6.7 there is a backport): https://fedorahosted.org/sssd/wiki/Releases/Notes-1.12.5
entry_cache_ sudo _timeout is useful or do i need refresh_expired_interval?
Here's another idea. If you run sudo periodically, you can tune the cache to be long enough and set entry_cache_nowait_percentage to apply so that the entry is returned from cache but refreshed on the background.

Ok, check it out.

Well, In my environment I've a single server that I've updated to 1.12.5, and timings I get are:
No cache: 2.87s Cache: 0.014s
Still a little painful. I will experiment with refresh_expired_interval...

to shamelessly thread-jack here, does anyone have a pointer for me, as to why $USER is not being expanded by autofs, when called from ldap? i have some direct maps working, but my indirect maps do not work as expected. i have tried $USER, ${USER} and {$USER} variations. i have tried putting it in the automountKey under auto.master, and in the automountKey under auto.indirect (which is called by the automountKey under auto.master) to no avail. any help would be appreciated.
