[c-nsp] vs tacacs+ and Nexus5K

This reminds me of once I had to access a customer's router and they sent me a mail with the username.
For this example lets use your username, his mail was something like this:

"You can log in with 26rt. The password is blahblah"

Then I tried several times to login as 26rt and couldn't get in!!
Until I went over the customer's mail again one more time and then tried to log in with "26rt." (pay attention to the ending dot)
Guess what? That was the problem, his username actually contained a dot at the end and I omitted it because we're always used to ignore the dot at the end of the sentence...

I'm not sure this is your case, I just thought it may be useful...

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 ??

/Arne
