Use samaccountname and userpriciplename for authentication

Hi all,

I am trying to find out if it is possible to use both IDs (samaccountname and userpriciplename) at the same time to authenticate a user against the portal. I have found out that by configuration either one can be used. Now I want to find out if it is possible to use both at the same time for authentication against the portal/ADS.

I assume that this can only be accomplished by modifying the com.sap.portal.runtime.logon.par.

Has anybody already done something similiar? Or can anyone point me to documentation describing how to access/search the ADS for such information using Java?

Thanks a alot for any input on this!

Best regards,

Helga
