Title: #616: become_user: add supplementary groups so ad provider can access keytab
Action: opened
PR body:
"""
For security reasons one might want to run providers as a non-privileged
user (say, _sssd). However some providers (in particular ad) might need
an access to restricted (non world-readable) files (for instance,
/etc/krb5.keytab). One of the possible ways to solve the problem is to
- add a special group (for instance, _keytab)
- set the owner:group of the file in question to root:_keytab
- set the permissions of the file in question to 640
- make the _sssd user a member of the _keytab group
For this to work become_user should assign supplementary groups, which
is what this patch does.

[sssd PR#5251][opened] [wip] subdomains: allow to inherit case_sensitive=Preserving
by pbrezina
URL: https://github.com/SSSD/sssd/pull/5251
Author: pbrezina
Title: #5251: [wip] subdomains: allow to inherit case_sensitive=Preserving
Action: opened
PR body:
"""
The first patch is just man page update to reflect current state.
I think it makes sense to be able to show subdomain names in
their original casing. Patches 2-3 make it work for AD provider.
Patch 4 makes it work for IPA provider. There is apparantely a bug
in winbind, but there is no link the any bugzilla so I do not know
if it was already fixed. The commit is four years old. This patch
requires case_sensitive=Preserving to be set also on the server,
otherwise it does not work. It can be enabled without the server setting
but we need to make nss_cmd_getpwnam_ex (and other _ex commands) to
always return case preserving name. So before I continue the work
I'd like to ask @sumit-bose if we can do it like this.

[sssd PR#5367][opened] pam: add pam_sss_gss module for gssapi authentication
by pbrezina
URL: https://github.com/SSSD/sssd/pull/5367
Author: pbrezina
Title: #5367: pam: add pam_sss_gss module for gssapi authentication
Action: opened
PR body:
"""
The module configuration and usage should be clear
from its manual page. Suggestions are welcome.
The main use case is to enable password-less authentication
for sudo where smartcards are not possible (because the
reader is not available in the target host).
It is not possible to set the service name or keytab at this
moment so the module relies on `host/hostname@REALM` where hostname
is provided by SSSD (based on the user's domain) and REALM
is determined by GSSAPI. This principal is already stored in
krb5_keytab location for IPA and AD providers so the functionality
is for free.
Because authorization is done by pam_sss and it is not needed
for the use case, I would implement configurable ticket names
and keytab location only when required by users.
