N.B. as per the discussion on the Janet-roaming mailing list a while 
back, and on this list a bit later - if you're running PEAP/MS-CHAP, 
even running LDAP on the inner tunnel will, currently, incur 3 LDAP 
lookups, one for each pass through the inner tunnel - EAP-identity, 
EAP-MSCHAP, EAP-success.

Once I've failed my exam tomorrow (haha! just kidding... I hope) I will 
have some free time, and will revisit the EAP code changes needed to 
make this not happen.

Or you could use the vilest unlang ever devised[1]

# stop processing authorize on eap identity or mschap success/fail
if ((EAP-Type == 1) || (EAP-Message =~ /^0x02..00061a..$/)) {
else {
   # rest if your inner EAP goes here



[1] Unlang may not actually be the vilest ever devised
