On one of my LDAP driver I am generating a password using the new 3.5 token.

I occasionally get this error:
LDAPException: Constraint Violation (19) Constraint Violation LDAPException: Server Message: Value of attribute "userpassword" contains extended (8-bit) characters: xxxxxxxxx LDAPException

Is this likely because in my password policy I have:
Allow non-US ASCII characters true

Just wanted to check before I go changing things.
