CentOS - Apr 2007 - usermod and useradd errors

I am not sure if anyone else has run into this, but i did today when
setting upo a samba server.

In an nutshell you get an error like: "usermod: invalid numeric
argument", or the user groups are never assigned, etc. So I have been
managing manually. I get the exact same symptoms, etc (but doing
things like appending groups, etc).

Apparently it can be fixed by downgrading Shadow package to 4.0.17,
however with a quick little "rpm -qa | grep shadow", I can see the
version with Centos 5 is shadow-utils-4.0.17-12.el5.

I have not spent much time digging in deeper as of yet, but wanted ot
see if any others have had this issue in Centos 5.

Is the command you are typing identical to the command in that link except
for the group name?

usermod -a groupname -G groupname username

If it is it looks like the error may be with including the groupname after
the -a.

I believe the command should just be :

usermod -a -G groupname username

Cheers!
