This is a restriction on Nexus with release 4. You cannot use usernames
starting with digits (the same applies for hostnames).
This is documented in CSCta00308

This should be fixed in release 4.2.3

Hi all.

Has anyone seen this before.
I have a user under a tacacs server that uses  the username 26rt.
This user doesn't work, all other users works fine. It seems that the
box accept the request but doen't login.
If I change the username to g6rt or r26tg etc., then it works fine.
It's the only user that I have that uses this "type" off name, so that's
why I haven't seen it before.
The funny thing is, the username works on all our IOS boxes. Is there a
known bug on NX-OS ??
