[Samba] primary group gets set to 100 on Samba AD server after a while

[Gerben Roest]

Hi,

using Samba 4.4.2, on the Samba AD server the users have their primary
group at 513 (domain users) but after a non-fixed time they get set to
100, like:


[root at sambaserver:~]# id john
uid=6032(DOMAIN\john) gid=513(DOMAIN\domain users)
groups=513(DOMAIN\domain users),1013(DOMAIN\sales)

<few minutes>

[root at sambaserver:~]# id john
uid=6032(DOMAIN\john) gid=513(DOMAIN\domain users)
groups=513(DOMAIN\domain users),1013(DOMAIN\sales)

<few minutes>

[root at sambaserver:~]# id john
uid=6032(DOMAIN\john) gid=100(DOMAIN\domain users)
groups=100(DOMAIN\domain users),1013(DOMAIN\sales)

then when I "net cache flush" do: they're back at 513... only for a while.

The Linux workstations always see the users at 513, this only happens on
the Samba server itself. This can happen with intervals of a few
minutes, but I've also seen it being "stable" for a few hours.

any ideas?

thanks,

Gerben
