[andreboscatto]

Resolves: #7173

[andreboscatto]

Before updating SSSD

allopez@alf:~/ws/repos/sssd-ci-containers$ ssh [email protected]@client.test
([email protected]@client.test) Password: 
Creating home directory for [email protected].
-sh-5.2$ ^C
-sh-5.2$ 
logout
Connection to client.test closed.

and it fails searching with all lower case mail attribute:

llopez@alf:~/ws/repos/sssd-ci-containers$ ssh [email protected]@client.test
([email protected]@client.test) Password: 
([email protected]@client.test) Password: 
([email protected]@client.test) Password: 

After updating SSSD

searching with all lower case mail attribute:

allopez@alf:~/ws/repos/sssd-ci-containers$ ssh [email protected]@client.test
([email protected]@client.test) Password: 
Last failed login: Wed Feb  7 12:59:24 UTC 2024 from 172.16.100.1 on ssh:notty
There were 4 failed login attempts since the last successful login.
Last login: Wed Feb  7 12:58:54 2024 from 172.16.100.1
-sh-5.2$ 
logout

searching with the exact mail attribute as registered:

allopez@alf:~/ws/repos/sssd-ci-containers$ ssh [email protected]@client.test
([email protected]@client.test) Password: 
Last login: Wed Feb  7 13:01:41 2024 from 172.16.100.1
-sh-5.2$ 
logout
Connection to client.test closed.

searching with all caps letter mail attribute:

allopez@alf:~/ws/repos/sssd-ci-containers$ ssh [email protected]@client.test
([email protected]@client.test) Password: 
Last login: Wed Feb  7 13:01:56 2024 from 172.16.100.1

Thank you so much for helping me with testing @aplopez :)

@andreboscatto, I removed branch: sssd-1-16 because patch won't apply there.
It has different sysdb versions - see

sssd/src/db/sysdb_private.h

Line 26 in 0fbeaa7

#define SYSDB_VERSION_0_22 "0.22"

If you want to fix 1-16 as well you need to backport manually and open explicit PR.

CI failure is not connected with the patch.

Thanks @andreboscatto, ACK
