[Pkg-utopia-maintainers] Bug#489738: dbus has problems with ldap groups for policies ("Unknown group "dev-usb" in message bus configuration file")

[Noel Köthe]

Package: dbus
Version: 1.2.1-2
Severity: important

Hello,

in /etc/dbus-1/system.d/hal.conf the group (from /etc/group) "plugdev"
gets the permission for the removal devices.
We are using LDAP for the account data and don't want to configure every
/etc/group on every machine. So I changed "plugdev" to the ldap group
"dev-usb".
Then I always get the error message:

Unknown group "dev-usb" in message bus configuration file

The group is there because "id" as a user shows me the group and "getent
group dev-usb" shows my user in the group list.

Here is the strace of a starting "dbus --system":

As you see it read the group cn=dev-usb,ou=Groups,ou=central with the
users but then it still writes "Unknown group \"dev-usb\" in messa"...

If you need more details/information tell me.
