Displayname template does not brake through

Hi everybody

According to http://help.sap.com/saphelp_nw04/helpdata/en/e4/c016987fbca343801d41096f124ec4/frameset.htm it should be possible to change the displayname template rather easily.

Unfortunately I can only get this displayname template to work for the users that are created in the portal, it doesn't work for users that are mapped from the LDAP!

At first I thought that this problem was caused by the mapping of displayname to displayname in the dataSourceConfiguratíon file:

from the configuration file as well? In relation to this string, what does the populateInitially="true" part of the string do?

Any help is greatly appreciated and will be rewarded.

Best regards,

Martin
