UPN on big ip f5 APM policy

Hi,

there is a mistake in this command. try this one.

set extension [string tolower [mcget {session.ssl.cert.x509extension}]];
return [string range $extension [expr {[string first "othername:upn<" $extension] +14}] [expr {[string last ">" $extension] -1}] ]; 

I guess you got it from this codeshare

There was an error I just solved. the string first was searching a uppercase word (UPN) in a lowercase string
