Switching UME datasource from LDAP to Database


Has anyone had any success switching the datasource from LDAP to portal database? I know it's documented as " not supported unless explicitly specified" in the relevant SAP note, but just checking to see if anyone has had any luck. If yes, could you please let us know the issues you faced?

I've have switched from:

- ABAP back to UME DB

and also from

- LDAP back to UME DB

Both where successful ...

As your already mention, and that is very important, it isn't supported.

one very important item is to know how your system was installed initially.

Because during the sapinst installation process at one time in the wizzard you are asked how to configure UME.

If that was the moment you chose to use LDAP (or ABAP) as datasource then you will not have the UME users like Administrator and Guest. If during the installation UME was chosen and after the installation was finished the UME was switched to LDAP then these users are still there and the chance that you will succeed in a successful switch is very high.
