The issue is resolved. In few UAT Appian database tables (CFG,GRP,USR), there were duplicate entries made for 'Administrator' id . Entries like 'GROUP_INDEXING_STRATEGY_VALUE, COLLAB_CONTENT_INDEXING_STRATEGY' value were duplicated. How it got entered is not known, may be because of database inconsistencies (there was some DB table space issue at that time in UAT). So, when Appian App server executes query to fetch these value from the above mentioned tables and it got a duplicate entry where its expects only a UNIQUE value. This was cause of the problem for both Tempo login issue and Site deployment issue (depends on COLAB_CONTENT_INDEXING_STRATEGY ). It was fixed with help of Appian Support Engineer by deleting the duplicate entries of 'Administrator' and re-starting the server.
