FreeRadius/LDAP Generic Reply Attribute

Hello,

I need to pass an odd reply attribute back to my Cisco router to limit DSL users speeds on the interface. I am moving from radiator to freeradius, we are going this fine on radiator from a mysql database.

The ldap entry in the directory is
radiusReplyItem: Cisco-Avpair = lcp:interface-config#1=rate-limit input 512000 96000 96000 conform-action continue exceed-action drop

It appears that it is being truncated at the "#" sign, is this field too long? or is a special character messing it up, is there anyway i can escape the special character if so?

Thanks for any help!



Here is the DEBUG, I have bolded the lines i noticed....
