Hi Tim:
Thanks for sharing your experience. I think I need to elaborate my requirement more as my requirement is same as well you described.
In my case as well user is prompted for AD credentials only but not SAP user master credentials in both the cases(LDAP and SAP user master were in synchronized). Its just he/she need to punch in credentials manually for both ECC and portal.
1) User login to Kiosk using shared credentials
2) When user punch AD credentials on logon pad of ECC , He/she should not be asked again credentials for Portal
3) When user punch AD credentials first time for portal system, he/she should not be asked again credentials for ECC system.
Can you please advise on how this can be done?
Thanks a lot .
