Hi,

I am testing the freeradius server, and try to clarify rules applied in freeradius.  In the following trials, I could not figure out how to make Autz-Type Ldap1 in authorize section to correctly set Auth-Type used in authentication without the help from “Auth-Type := Ldap1”.   

With the following entry in users file,

**************

DEFAULT Called-Station-Id =~ ".*Guest@myu", Autz-Type := Ldap1, Auth-Type := Ldap1

**************

the user authentication worked fine.

Below is the debug output.
