how to get this logentry correct

[Arran Cudbard-Bell]

Hmm yes, pretty out of date way of doing things, the problem is you're explicitly forcing authentication to succeed, and calling the exec module really late...

Get rid of the files call, or just use it to set the reply message i.e. Don't use Auth-Type = Accept.

See here for a guide:
http://wiki.freeradius.org/multiOTP+HOWTO

If you're using FR 2.1.11  just remove '${policy.multiotp_prefix}' from regexp in the authorize section
If you're using a version lower than FR 2.1.11, please upgrade.
