Triage report (2021-09-01)

[Paride Legovini]

Two interesting bugs to mention today.

# LP: #1942195 [samba]: Installing Samba unexpectedly adds many unknown 
local users to sambashare group

This is happening because samba.postinst does:

for USER in `getent group admin | cut -f4 -d:`; do
     adduser "$USER" sambashare

but the 'admin' group doesn't exist anymore in Ubuntu, and in this case 
it happens to be a remote group, leading to the described result. My 
proposal is to drop the auto-adduser mechanism altogether. See my 
comment there for more details & reasoning.

I marked this server-triage-discuss and subscribed the team, but didn't 
mark it Triaged yet.

# LP: #1941857 [sssd]: sssd does not renew user TGT even when 
krb5_renew_internal and _lifetime are set.

This is a bit out of my comfort zone, but it's a good bug report and the 
user compiled Focal's sssd on Bionic with no changes and found out that 
the issue is gone. I asked the user to confirm some of my assumptions 
and hinted that more testing on past Ubuntu sssd releases on his setup 
may be very valuable. Left this Incomplete for the moment.

Cheers,
