I've recently upgrade iRedAdmin-Pro-LDAP to version 2.3.1 on Centos 6.
I've added the following settings to settings.py:
LOCAL_TIMEZONE = 'GMT+01:00'
DEFAULT_PASSWORD_SCHEME = 'PLAIN'
STORE_PASSWORD_IN_PLAIN_TEXT = True
HASHES_WITHOUT_PREFIXED_PASSWORD_SCHEME = ['NTLM', 'PLAIN']
PASSWORD_HAS_UPPERCASE = False
PASSWORD_HAS_SPECIAL_CHAR = False
MAILDIR_HASHED = False
Most of it seems to work but it still adds the prefixed password scheme to the password. When I manually add the password in phpLDAPadmin the user can login, when entered in iRedAdmin-Pro it tells me the password is incorrect.
It also seems the LDIF export is not updated immediately.
