User authentication via LDAP using SAPGui

Hi All,

we get user requirement for User Authentication to SAP ECC (ABAP) Stack, we tried setting User Synchronization with LDAP tcode until we can create user automatically from LDAP server

the problem are :

1. we are confuse, how to mapping attribute between SAP and LDAP about "password"
2. status of password is deactivate at SU01
3. can we logon to SAP with LDAP password automatically by runtime?

as far we read many article, LDAP is very limited function, this tcode only to User Synchronization without Password.

please help

regards,
