I created a new PO on port 1678 but can't login to it

I have just 2 users created 1 in PO1 and 1 in PO2

I can login to PO1 just fine

If I try to login to PO2 with correct user I get an error saying user can't
be found!

I loaded PO with --show switch and I can see an entry for the user but no
error on POA screen - client report the error

If I try to connect to PO1 user into PO2 (with port 1678) - the login shows
up on PO2! and client loads ok
