Re: IDB Backup failure post upgrading to 9.0.8

If you change the credentials used by the IDB service you need to update the name mappings in ProgramData\OmniBack\server\db80\pg\pg_ident.conf.  (You can have more than one mapping.)

For example:

# MAPNAME SYSTEM-USERNAME PG-USERNAME
hpdpidb          domain\DP_dom_account hpdp
hpdpidb          DP_local_account hpdp
hpdpidb          SYSTEM   hpdp
