Problems in Changing LDAP (AD) Initial Password from Portal

Question

Hello ,
We are using EP 7.01 SP 05 with Microsoft AD as our user data store (flat structure).
For newly created users on AD, we are wanting them to be able to change their initial passwords from portal (on their first logon).
SSL is set up between EP and AD.
The user we are using to access LDAP has write privileges.
We are using a standard configuration file (writeable version) (dataSourceConfiguration_ads_writeable_db.xml)
We are able to modify users from User Administration console (including password change) without any problem.
However, there are two problems we are facing:
1. If the flag "User must change password at first logon" is set on AD/LDAP, then on Portal the user is not getting prompted for changing password - and User authentication failed
2. If the flag "User must change password at first logon" is NOT set on AD/LDAP, then - User is getting prompted to change the password" - however password change is not going through successfully - Error says - "Missing".
From logs I can see the following error:
#1.5#0050568767DE006B0000000700005D7C00048EC433D5B0FC#1282873241046#com.sap.security.core.persistence#sap.com/irj#com.sap.security.core.persistence.[cf=com.sap.security.core.persistence.datasource.imp.LDAPPersistence][md=changePassword][cl=64495]#Guest#0#SAP J2EE Engine JTA Transaction : [044ffffffd35700451]#n/a##19ae55e0b17c11dfb0d00050568767de#SAPEngine_Application_Thread[impl:3]_23##0#0#Error##Java###Can not change password

Can any one pls suggest what is this error about and what I am missing.

Hello All,
Thank you for your time and valuable replies.
I got rid of the "Missing" error and now I am one step away from the solution.
Now I am at a stage where: (for a user with initial password on LDAP)
1. In AD if "User needs to change password on next logon" flag is NOT set - user can successfully logon to portal. (without being prompted for password change)
2. In AD if "User needs to change password on next logon" flag is set - then user cannot logon to portal - I get User authentication failed error.
I have went through a lot of discussions around this topic on SDN and different SAP Notes. I have tried to maintain UME Security policy as close as possible to LDAP (I cannot make it exactly same due to some differences in LDAP and UME).
However, when and administrator can change passwords from UME successfully without any problem - it means that:
- Security policy is being met
- Service user used to communicate to LDAP has all the required access
The only missing piece of the puzzle is how to enable the users to be able to change their passwords (with initial or expired passwords).
According to Note 865399 - the default value for The property ume.ldap.access.set_pwd is TRUE.
Also the property ume.ldap.access.pwd.via.usercontext can only be TRUE when ume.ldap.access.set_pwd is set to FALSE.
So, I have tried setting the following without any success:
<ume.ldap.access.pwd.via.usercontext>true</ume.ldap.access.pwd.via.usercontext>
<ume.ldap.access.set_pwd>false</ume.ldap.access.set_pwd>
Thanks,
