Default user/pass not working on NSO

Hej
I have performed a local install, but I can not login to the GUI using admin/admin.

I can login to CLI with "ncs_cli -C -u admin" , but when I do "show run", all I see is snmp configuration on the device. I can not see AAA or configure it.

cisco@Ubuntu-2:~$ ncs --status | grep status

You're not supplying a group, so the default is whatever the `groups` command defaults to.

Try:

ncs_cli -C -u admin -g admin

I have tried that command, but I am getting the same result. Nothing in config other than snmp, and can not login to GUI

I have the impression you are having some permissions issues, what happens when you login using the --noaaa option?

ncs_cli -C -u admin -g admin --noaa

l recommend you to take a look at this Learning Lab https://developer.cisco.com/learning/tracks/get_started_with_nso/nso-labs/learn-nso-with-netsim/setting-up-nso/ where you can find a local install of NSO, it can help you to compare defaults and can help you to get started.

I can still login.

cisco@Ubuntu-2:~$ ncs_cli -C -u admin -g admin --noaa

User admin failed to log in 1 times!
admin connected from 10.255.0.96 using ssh on Ubuntu-2

But you should be able to see aaa and configure it. Can you do that?

No, that is the main problem. When I say "show run" on ncs_cli, I only get snmp, nothing else. If I try to config and put aaa I get the below error

admin@ncs(config)# aaa ?
^
% Invalid input detected at '^' marker.

Depending on what you did on setup it is hard to say what is going on.

If you want to recover access so to speak, search for aaa_init.xml somewhere in install dir then use ncs_load to load it in. That file should have enough config to allow admin to work properly.

In the default ncs.conf, the /ncs-config/cdb/init-path is set to ${NCS_DIR}/var/ncs/cdb, where the default aaa_init.xml file is located. If the configuration from the aaa_init.xml file is not loaded and the aaa and nacm config is not configured, there will be no config under aaa or nacm, so unless you use the --noaaa flag with ncs_cli, the user will not be allowed to access the nodes.
Note that ~~--noaa~~ should be --noaaa
