Hi,

I had the same problem in an earlier version we used and got the reply from Micro Focus support that in versions earlier than 2019.05 there is not a way to reset the password from the gui. Strange but true

But for 2019.05 and later, this should work:
https://docs.microfocus.com/itom/SMAX:2019.02/ChangeSuiteAdminPassword

For versions earlier than 2019.05 I got this guide from Micro Focus support to reset the password:

Reset the password from the command line:

First you need to expose a service (and port) to external

Create the file postgres-suite-expose.yaml with this content
~~~
apiVersion: v1
kind: Service
metadata:
 name: postgres-suite-expose
spec:
 type: NodePort
 ports:
 - port: 5432
   targetPort: 5432
   nodePort: 35433                 <------- node port
 selector:
  name: pgpool                     <------- selector condition
~~~
Start the service: 

kubectl create -f postgres-suite-expose.yaml -n itsma1

1.     Kubectl get ns (take note of itsma name)

2.     kubectl get pods -n itsma-(from step 1) | grep idm

3.     kubectl exec -it idm-(from step 2) -n itsma-(from step 1)  -c idm sh

4.     psql -U idm -h (fqdn of localhost) -p (node port from the exposed service)

5.     select * from Database_User where name like 'suite-admin';

6.     select name,password from Database_User where name like 'suite%';

7.     update database_user set password='D9 T/1Khc6LmT9tLhwyJ8oFsIReGsQEzrkXW pjHGPY=', salt='Zdgxptm0OnwjJEFgL5MQeWbNJ9aThG/SyIvCvvuUI E=' where name='suite-admin';

8.     commit;

Then password will be Admin_1234

(Micro Focus support can give more information regarding the subject)

Hi,
I can confirm this solution is valid up to 2021.05

One point that may cause trouble (specially if the password was expired): this method doesn't change the values of modified_date, password_renew_date and password_expired_date. Consider to manually change those values in the DB as well if you have problems with just password and salt
