1603600 - Authentication fails, users expired LDAP directory passwords

• The User Management Engine (UME) of the SAP Netweaver AS Java is configured to use one or more LDAP directories as its datasource(s).
• The LDAP directory password of one or more users has expired or one or more users have been newly created in the LDAP directory and LDAP directory security policy deems that such users must change their passwords from their initial values at the time of first successful authentication
• When a user whose LDAP directory password is in one of the aforementioned states tries to login to an application that uses UME authentication e.g Netweaver Administrator, Enterprise Portal, User Management, a message 'User Authentication failed' is displayed and no password change form is presented to the user.
