I want to connect to LDAP, via an Integration Server Adapter. Can somebody tell me how to do this?
The only documentation I find on this topic, concerns an Enterprise Adapter.
Check the IS Administrator’s guide Chapter 9.
Actually that information is in Chapter 8 of the IS Administrators Guide v.61
The question was, how to connect to LDAP as an EIS system I think not to authenticate and authorizate IS users.
The answer is: Look inside webMethods Integration Server Built-In Services Reference pdf there is a quite well described LDAP folder in wmPublic package.
Of course, if you are looking for LDAP adpater like JDBC adapter is, the answer is: There is no such adapter 
The Enterprise version of LDAP adapter allows several configured operations to connect and retrieve information from LDAP.
For Integration Server there is no such thing as an LDAP adapter but like maciej.leks mentioned there are built-in services under WmPublic package → pub.ldap built-in services.
Thank you,
Muthu.
Can anybody tell me that from where can I get the WmEnterpriseLDAPAdapter_en.exe ?
Neeraj,
The Enterprise LDAP Adapter has been superceded by the ldap built-in services in Integration Server.
