So - is this a fresh CABI(Jasper) install - and there is no integration done via CA Spectrum integration (OC-server with ReportManager option - then Report Manager configuration dialogs). By initial default installation the CABI(Jasper) is NOT syncing any user account/models from Spectrum (as it just does not know anything about it). Doing the first time a CABI integration the OC-server hosting this integration is "sending" user-model information from Spectrum into the CABI context.
Up to this time there is only the Administrator account (superuser;superuser) valid.
There is also the option to configure CABI(Jasper) with enabled SSO/LDAP.
Is this matching here? hth .. cheers, Joerg
