Regarding TACACS configuration on Aruba Switches

[Vijay2405]

Hi All,

I have set up a tacacs + server on a linux VM running CENT OS and trying to get the authentication done via the Tacacs server. I followed the link https://networklessons.com/uncategorized/how-to-install-tacacs-on-linux-centos to bring up the Tacacs and configrued the following on the switch.

tacacs-server key ciphertext AQBapX79Y6gZ1SphPHKhUeF0EIF4G9MjiSSP56vQlEB9/XXlCAAAAOd/m6NxF/R9
tacacs-server timeout 30
tacacs-server auth-type chap
!
!
tacacs-server host 10.X.X.X vrf mgmt
aaa authentication allow-fail-through
!
aaa group server tacacs ta
server 10.X.X,X vrf mgmt
!
!
aaa authentication login default group ta

I could see that the messages are reaching the tacacs server on every login attempt but it always says 

Aug 24 23:44:09 projt-syslog-server-automation tac_plus[10531]: connect from 10.x.x.x [10.x.x.x]
Aug 24 23:44:09 projt-syslog-server-automation tac_plus[10531]: login failure: admin 10.x.x.x (10.x.x.x) ssh

Not sure if I;m missing anything on the config. could someone kindly educate if I'm missing anything?
