@Joe Lupo, try this code:

set subject [split [mcget {session.ssl.cert.subject}] ",="]; 
foreach {name value} $subject {
    if {[string trim $name] eq "CN"} { 
        return [join [lrange [split [string trim $value] "."] 0 1] "."]; 
    } 
}

the CN is split to a list with dot as separator (

split text "."
)... then the first 2 words (
lrange list 0 1
) are converted to string with dot between list items (
join list "."
) ...

if there is no dot in CN, the whole string will be returned.
