SSPR 2.0 HF1a
Enforce Microsoft AD password complexity set to true
User is not able to change the password more than once in a day in SSPR.
In the "change password" screen, accessed directly from the SSPR main menu, trying to change the password more than once a day loops the user back to the SSPR change password screen without changing the password. LDAP error 19 (constraint violation) shows in the error log.
By default, the Active Directory password policy sets "Minimum password age" to one day. This means that a user must use a password for one day before changing it.
