While an Identity has too many correlated accounts for same application, in the Manage User Access Select Accounts, the GUI may not be that user friendly, user might have hard time to find out the target account to be selected.
We can adjust the SailPointClassicBundle.js and SailPointBundle.js :
<label>Search: </label><input type="text" class="form-control" ng-model="searchText"/><br/> <div ng-repeat="accountInfo in ctrl.getCurrentStep().provisioningTarget.accountInfos | filter:searchText”>\n
Then restart the tomcat.
Then it should work as expected.
P.S. This is tested on IIQ 8.1
Thanks and Regards,
