I'm facing the following problem.
A file is read by an ABAP-program, from an external system and the entries (user names, e-mail addresses, etc) are fed into our R/3 system (SU01).
Untill now this was sufficient. But now we're trying to implement Single Sign On, so we also need to fill the field krb5principalname, which is used in the Portal.
I've looked everywhere, but I have no idea how to accomplish this. The field krb5principalname is (as far as I can tell) only known in the JAVA stack.
Does anyone have an idea how I could fill this field from an ABAP-program ?
As a second solution I've tried the user import utility from the Portal, but somehow this doesn't let me import "customised information" fields.
Your help is much appreciated !
