Setting 'samaccountname' in UME <-> LDAP integration

Hello All,

Portal version = EP7 SP9

We have configured UME with MS Active Directory successfully, except for the setting of 'samaccountname' in the parameter - Use Unique Attribute for UME Unique ID

Could you please guide me as to what will happen if I set this parameter with samaccountname now?

I did check SAP Note # 777640 but it mentions EP 6

Awaiting Reply.

Regards,

Ritu
