Hello,
Having some trouble getting this formatted properly for a site we're trying to add into Okta, I've created a new mapping under From Okta to > App for the sAMAccountName, and then I need to append @SOMETHING without a .com at the end of it. I saw a few things on the community here but am having some trouble piecing them together to get this to work.
This is what I have currently set as the attribute for the sAMAccountName mapping:
substringBefore(user.login,'@')+"@SOMETHINGHERE"
I get an error when I type in a username to test it that says "Invalid Property sAMAccountName in expression org.springframework.expression.spel.standard.SpelExpression@7e5d105b"
Would anyone be able to assist with the formatting on this? I've checked out the following links but this seems to be a bit outside of their scope.

Thank you!

Hi Jonathan!
Thank you for posting on our community.
This is an interesting behavior that you've experienced. May I ask if the samAccountName username format was over rode on the Sign On tab of the application that you're trying to add into Okta?
Or is this looking at a Directory Integration?
Either way, I would recommend using the Application Username Format setting for achieving this.
If this will not be helpful, I will recommend opening a support ticket with us and we can schedule a screen sharing session to assess what you are trying to implement and achieve sweet resolution.
Thank you,
