You may see this error while installing Visualizer 12.1 and following errors may appear in the stdlog file:
servername sda 3640 SIGNIFICANT sda.cpp 1884 Policies are initialized properly.servername boplgin 3644 ERROR bplaccess.c 3155 AHD04020: Login failed for userid (Administrator); no default role found for session type (3)servername sda 3640 ERROR bpserver.c 546 Session ID set to zero in ActiveSession for user Administrator
To resolve the issue, make sure that the default role for the Proxy Contact in the CA_CMDB_VISUALIZER Web Sevices Access Policy is set. Also ensure there are no duplicate contacts. If there are any contacts with duplicate userids, change the system login name on one of the contacts and make it inactive.
Also, verify if the correct user id is defined under proxy contact of CA_CMDB_VISUALIZER policy:
Login to CMDB and go to Administration tab.
