multiOTP - /etc/freeradius/policy.conf[33]: Expecting section start brace '{' after "else if"

[Timothy]

Thanks in advance for any assistance!

System: Ubuntu 14.0.4 LTS, FreeRADIUS installed from apt-get install.

FreeRADIUS works fine for what we have been using it for: MSCHAPV2 &
various types of EAP against AD.  We would like to add multiOTP to the mix.

multiOTP testing (not using FreeRADIUS) works fine from the command line.

After doing all of the steps from the guide (
http://wiki.freeradius.org/guide/multiOTP-HOWTO), I get the following error

/etc/freeradius/policy.conf[33]: Expecting section start brace '{' after
"else if"
Errors reading /etc/freeradius/radiusd.conf
--------------------------------------------------------------------------------------

The policy has been copied verbatim from the multiOTP howto, and inserted
above the existing policy.  The line in question is this:

>> else if (!control:Auth-Type && User-Password =~
/^${policy.multiotp_prefix}([0-9]{10})$/) {

if I change it to this (adding another closing bracket), FreeRadius will
start, but then I get a different error when doing a radtest -t pap from
the command line

>> else {
>>      if (!control:Auth-Type && User-Password =~
/^${policy.multiotp_prefix}([0-9]{10})$/) {

error on radtest:

? Evaluating (control:Auth-Type == 'MS-CHAP') -> FALSE
+++? if (control:Auth-Type == 'MS-CHAP') -> FALSE
+++- entering else else {...}
++++? if (!control:Auth-Type && User-Password =~
/^${policy.multiotp_prefix}([0-9]{10})$/)
? Evaluating !(control:Auth-Type ) -> TRUE
ERROR: Failed compiling regular expression: Invalid preceding regular
expression
+++- else else returns noop
++- policy multiotp.authorize returns noop

If I try any other RegEx (like nested if's), it still has the "invalid
preceding regular expression" error.

My concern is that the policy.conf modification in the HowTo might not work
in my case.

If someone can shed some light on this matter, I would gratefully
appreciate it!
