What Linux are you running?  At least under 7.1, I just added a user with the name thisisalongname with no problem.

I think you may find that only the first 8 chars are recognised. I think this is the same with other *nix platforms as well.

jools:
thisisalongname user account is stored with this name in the /etc/passwd file and the entire name is used to login (per my previous comment).  Still would like to know what Unix mphiri is using.

OK, it has been a long time since I did anything with userid anyway.

mphiri may be using an older version of unix (login) that only looks at the first 8 chars but as you say, knowing what they use will help.

I am running redhat 7.2. dkloes seems to be on the right track. do I need to edit /etc/passwd to add these long file names?

I used the useradd utility.  To take the defaults:

useradd thisisalongname

Then run passwd to set the password.
