Nexus TACACS & AAA problem

Unanswered Question
Mar 9th, 2010


I'm having problems getting our Nexus 7000 to authenticate users from our Windows domain. If I set up a user within the ACS server and use the CiscoSecure database for password authentication it works fine.

In the logs on the nexus I receive the following messages when logging on using my windows account.

%AUTHPRIV-3-SYSTEM_MSG: Unable to create temporary user 16894. Error 0x404a0036  - login[20923]

%AUTHPRIV-3-SYSTEM_MSG: pam_aaa:Authentication failed for user 16894 from - login[20923]

We can log on to all other Cisco OS devices using windows domain accounts, its just the Nexus.

Any help much appreciated.



I have this problem too.

Usernames starting with a number (16894 in the example below) are not allowed on NX-OS.

Thanks for letting me know, I've spent ages trying to figure this out. Do you know of any way around this? I was planing to upgrade the NX-IOS to version 4.2.4 to but I presume this won't make any difference?
