Bug#310976: davfs2: convert usernames/groupsnames to uid/gid

[Guido Guenther]

Package: davfs2
Version: 0.2.3-1
Severity: wishlist
Tags: patch

Hi,
the attached patch allows to give usernames/groupnames instead of uid
and gid for the uid and gid options, with this patch you can write:

mount.davfs http://foo/bar /mnt -ouid=admin,gid=src

instead of having to lookup the group and user by hand. This makes it
easier to integrate things into pam_mount, etc.
Cheers,
 -- Guido
