Session token may be filtered by input validator

What steps will reproduce the problem?
1. get a random session token from PWM
2. follow the redirect to validate your client
3. the session token after the redirect will be filtered if it contains the 
string "href"

What version of PWM are you using?
trunk

Please paste any error log messages below:

The session validation token contains the keyword “href” which is 
considered malicious by the input validator, therefore the input is discarded 
before the session validator can process it and the user ends in a redirect 
loop.
