NMAS error on Forgotten Password usage

What steps will reproduce the problem?
1. Configure PWM to read the password policy from eDir (Password Policy Source 
= LDAP) and allow user to recover forgotten password.
2. Login as user and set responses.
3. Try to recover forgotten password - answer to the Challenges
4. The Change Password form now opens
5. Clcik on auto generate new password

What is the expected output? 
After entering a new password that complies to the eDir password policy, the 
form should allow to save the new password.

What do you see instead?
Although the entered password does comply to the Password Policy (manula 
check), I get the following message:

"New password does not meet requirements. Please try using a different 
password."

Catalina.out throws an NMAS -1648 error:
