Regex for parsing LDAP attribute string value

I'm trying to pull a specific variable from an LDAP string attribute. The attribute is proxyAddresses, I need the value of "SMTP:" (case sensitive). I'm using the variable assign option in the VPE. Here is the crappy expression I'm using to create the session.custom.sso.smtp session variable.

 

session.custom.sso.smtp = expr { [lindex [split [mcget {session.ad.last.attr.proxyAddresses}] "SMTP:"] 1] }

 

I'm only getting 3 character of the attribute. Here is a sample of the proxyAddress attribute contents;

 

| sip:ROCKKI@rockservices.com | smtp:ROCKKI@rockservices.appacheonline.com | smtp:Kid_Rock@rockservices.com | smtp:Kid.Rock@rockservices.com | SMTP:ROCKKI@rockservices.com |

 

Thx

    Hi,

    in APM variable, 

    |
    character is the list delimiter....

    you can try the following expression:

    foreach address [mcget {session.ad.last.attr.proxyAddresses}] {
    if { [scan $address {SMTP:%s} mail] } {
        return $mail
    }
}
