Login BSP with LDAP

Hi!

We are accesing to several BSPs through an ITS. ITS valids the user in LDAP and then create a logon to our BSP.

We are studying to eliminate the call to ITS. We want to check the user in LDAP without ITS, but we don't find information about it.

Anyone has implemented this in its system something like this? Where can we find information for LDAP + BSP?

We have SAP 4.7 with WAS 6.20

Thanks in advance.
