Package: winbind
Version: 2:4.16.1+mag-1
Severity: important
Dear Maintainer,
I have rebuilt samba 4.16.1 packages as I am including a samba INTERNAL DNS
patch, bt I have not altered the packaging significantly other than this, and
have not touched winbind
I have been finding that when I login to the machine using a user from samba
AD,with groups from samba AD, none of those AD groups that user is a member of
show up in the output from the 'groups' command.
Further more:
shalom: -root- [/home/admin]
# wbinfo -r grantma
failed to call wbcGetGroups: WBC_ERR_DOMAIN_NOT_FOUND
Could not get groups for user grantma
And in the samba logs:
[2022/06/02 16:30:45.687576, 0]
../../source3/winbindd/winbindd_samr.c:71(open_internal_samr_conn)
open_internal_samr_conn: Could not connect to samr pipe:
NT_STATUS_ACCESS_DENIED
The above works fine when the samba package is installed along with winbind.
After the call find that the following programs are running:
shalom: -root- [/home/admin]
# ps -ef | grep samba
root 139564 1 0 16:29 ? 00:00:00

--worker-index=8 --debuglevel=0
root 139583 136857 0 16:29 pts/5 00:00:00 grep samba
When the above binaries permisions are set by:
shalom: -root- [/home/admin]
# chmod 400 /usr/libexec/samba/samba-dcerpcd /usr/libexec/samba/rpcd_lsad
the following happens:
shalom: -root- [/home/admin]
# chmod 400 /usr/libexec/samba/samba-dcerpcd /usr/libexec/samba/rpcd_lsad
It appears that wind bind needs samba-dcerpcd and rpcd_lsad to function
correctly. Could these binaries and dependent libraries be moved to the
winbind package please?
Thank you!
Matt Grant
