Mass authorization maintenance in JAVA

Hello all,

System is JAVA-only landscape (e.g. ESR). Identity management is configured to use LDAP (data source = Microsoft ADS Read-Only (Flat Hierarchy) + Database).

There will be around 300 users where we have to assign specifc UME role.

Question - is there a way of doing like 'mass maintenance', like upload from spreadsheet?

Thanks,

Terry
