% error in authentication

[Louis Adams]

HI,

I am trying to enable ssh on my cisco 3850 switch.  When i changed to aaa new-model and i try to ssh to the switch i get the username prompt and then i put in the username.  the first thing it says is "Using keyboard-interactive authentication."  then it prompts me for password.  I put the password in and it takes me to usermode.  Then when I type en to get to enable mode it gives me the following error.  "% error in authentication.  Currently the only way i can access privileged mode is by the console.  We do not have a tac+ server. We are just use local.  I tried to do some research and used the command aaa authentication enable default local in global config and that did not change anything.  Any Ideas what i am missing.

Hi,

Try these commands and test again:

username <username> privilege 15 password 7 <password>

aaa new-model

aaa authentication login default local

aaa authentication enable default enable

HTH

Thanks that was it.  Works as expected now.

Actually I also had to issue the following command to stop the keyboard interactive message.

no ip ssh server authenticate user keyboard

and then I had forgotten to create the enable secret command.  once I did that all was good.

Glad to know it is all working now.

Hello Reza Sharifi, I am facing with the same issue as below. When I access the SW by consol and after login with local admin and password i get this below mode and I am not able to change the configuration. the Switch is in stack configuration. Looking for your advice.
