APM variable assign and if statement

Hi,

the code provided by Kai is good and working fine.

I think you can change the other part of the variable assign with regex

if {[regexp {othername:UPN<[^@]+@([^>]+)>} [mcget {session.ssl.cert.x509extension}] UPNFull current_domain]} {
    if { $current_domain equals "local.domain" } then {
        return "abc.remote" ; 
    } else { 
        return $current_domain ; 
    } ;
} else {return ""}

regex is almost every time worse than string compare like equals, but with split, foreach, string first commands, but regex is better than this code.
