Description of problem:
Gkrellmd (from gkrellm-daemon) can not started due to gkrellmd user 
is absent.

I discovered the problem and found group conflict.
authd makes system group with id = 101 (if installed before any 
package that use groupadd command in preinstall scriptlet).
However, gkrellm-daemon try to create group with statical id = 101.
If id was busy, group can not be created.

Version-Release number of selected component (if applicable):
authd-1.4.1-1.fc3
gkrellm-2.2.2

How reproducible:
Setup authd on standart installed system.
Then setup gkrellm-daemon. Try to start gkrellmd by service gkrellmd 
start.

Solution:
Reserve some gid for authd (ident) or remove static gid from gkrellm.

Additional info:
$ grep 101 /etc/group /etc/passwd
/etc/group:ident:x:101:
/etc/passwd:ident:!!:100:101::/home/ident:/sbin/nologin
