Hello Titya

The only thing I can suggest at this point is to verify that your configuration is correct using [this Cisco documentation](https://www.cisco.com/c/en/us/td/docs/switches/datacenter/nexus3000/sw/security/503_u1_1/b_Cisco_n3k_security_cg_503_u1_1/b_Cisco_n3k_security_cg_503_u1_1_chapter_0100.pdf) for the specific requirements.

By default, the local database is used. Make sure you have indicated the location of the TACACS server and have placed that first in the `aaa authorization` command.

I hope this has been helpful!

Laz

One thing I see in your config is that you configure group “abc” and then specify group “today” :

```
aaa group server tacacs+ abc
aaa authentication login default group today

```

If you want to troubleshoot this, debugging is very helpful:

```
NX1# debug aaa ?
  aaa-requests Aaa request debug
  all Enable all the debug flags
  conf-events Aaa configuration events
  errors Aaa errors
  events Aaa events debug
  mts Configure Tx/Rx packets of MTS

```

Set it to “all” and you’ll probably see an error message when you attempt to authenticate.
