Hi all,

I found a BUG in libuser-0.56.9.
<https://fedorahosted.org/libuser/attachment/wiki/LibuserDownloads/libuser-0.56.9.tar.bz2>
When I add a username consists of only digitals, like "1234", error happens.

Reproduce steps:
1 luseradd 1234
2 Group 1234 does not exist

But when I use "useradd 1234" command, no error happens.

I find the reason that luseradd converts "1234" from string to a long
int, and uses it as gid.
But when luseradd uses lu_group_lookup_id(ctx, gidNumber, groupEnt,
&error) to find the group,
error happens, because there is not such a group.

Regards!

Pan Weiping
