invalid operator in auth section

Hi ! I have a question, What is the operator I can use in the post auth section for this matching Nas-Port-id =* "tty" In the users file it is works, but I want use it in post auth section. The regular expression ("tty[0-9]") could be good but i don't know how to do. Module: Checking post-auth {...} for more modules to load Expected comparison at: =* /usr/local/radius/etc/raddb/sites-enabled/default[401]: Errors parsing post-auth section. Is any idea? Thank you!
