we have successfully implemented SPnego and have our AD Forest (Global Catalog) available in the portal (selectively by setting the AD field we defined for UME unique ID in ConfigTool).
Now: In the Datasource-Configuration XML there is a mapping for "uniquename" to a physical attribute (in our case samaccountname). What does this exactly do? I can see the attribute in the Portal in the User Management as "LogonID". Is there any rule to which attribute I should map uniquename? If I search for users, I can find them anyway, I do not need to search for the samaccountname.
Any help appreciated.
