New User In OTM 6.3 Not Able To Login

Hi All,

I finished installing OTM 6.3 successfully.
I am able to login using DBA.ADMIN, but the problem here is I created two new domains
1. AAA
2. BBB
Now I am trying to login using AAA.ADMIN/CHANGEME username/password but the application throws an error "A connection to the server could not be established: null (user=UNILEVER.ADMIN)"

So I tried creating a new user in DBA domain as DBA.READONLY/CHANGEME now if it try to login using this credentials I am getting the same error.

If I query the list of available users I am able to see all the users I have created.

Please let me know if I have missed anything.

Thanks,
Vishwamber Shetty
