Solved this via SQL. Note that updating the profile via the GUI after applying the SQL statement will remove the Username and Password
run sql update ucserviceprofiledetailxml set xml = '<UseUDS>false</UseUDS><UseUserCredential>false</UseUserCredential><DN>INSERT USERNAME</DN><Password>INSERT PASSWORD</Password><SearchContext1>INSERT SEARCH CONTEXT</SearchContext1><SearchContext2></SearchContext2><SearchContext3></SearchContext3><RecursiveSearch1>true</RecursiveSearch1><SearchTimeout>5</SearchTimeout><BaseFilter></BaseFilter><PredictiveSearchFilter></PredictiveSearchFilter><AllowJabberUserstoSearchandAddSecurityGroups>false</AllowJabberUserstoSearchandAddSecurityGroups>' where pkid = 'INSERT PKID OF PROFILE'
