Bug#605396: delgroup --system gdm fails on gdm remove, on LDAP enabled box

[Witold Baryluk]

Package: gdm
Version: 2.20.11-2
Severity: important

Hi.

On my box with LDAP nss, gdm.postrm fails

root at escalus:~# LC_ALL=C dpkg -P gdm
(Reading database ... 439702 files and directories currently installed.)
Removing gdm ...
Purging configuration files for gdm ...

dpkg: error processing gdm (--purge):

Errors were encountered while processing:

root at escalus:~# getent group gdm
gdm:x:112:
root at escalus:~#
root at escalus:~# grep gdm /etc/group
root at escalus:~# 

Which means that gdm group is defined on LDAP box.
But using groupdel for them will not work (for few reasons).

Ignoring groupdel error resolves my problem, and upgrade can process without any issues.

Thanks.
