Hey Sumit,

I'll get you the logs next week...however, we only have them for debug=9.  The 
guy I was working with just left for the weekend.  We have quite the 
collection.  

What we're seeing for lookups by email is pretty consistently 500ms to 1s where 
lookups by account takes ~20ms once cached.  Initial lookups for uncached ids 
are comparable.  Is there any way to tell sssd not to break apart the address 
and use it as given?

There are likely other areas that are likely less than optimally configured as 
well since this was a learning experience when we switched over to sssd.

Can you specify how fast is was before and after?

SSSD has to break the name apart to figure out if the domain part
belongs to a know or unknown domain. If the domain is unknown SSSD
assumes that the name is an email address. In the other case it assumes
a user name first and falls back to an email address is a matching user
wasn't found.

Can you send SSSD's pam and domain logs with debug_level=10 (see
https://docs.pagure.org/SSSD.sssd/users/troubleshooting.html for
details). Feel free to send them to me directly if you do not want to
share them on a public list.
