To set up the use of Microsoft NTLM with SAP systems, you need to activate the SAP Logon option on each SAP front end. The SAP Logon window includes a list of systems or machines that you can log on to. For each of the systems or machines in the list for which you want to implement SSO, follow the procedure below.
You have completed Configuring the Application Server.
The gssntlm.dll file is located on sapserv<x> in the directory /general/misc/security/gssntlm.
The variable specifies the path to the gssntlm.dll file. You can do this using one of the following methods:
Variable: SNC_LIB
Value: <DRIVE>:\<SAPGUI_PATH>\gssntlm.dll
This is the default file name that SNC uses when SNC_LIB is neither entered on the command line nor available in the environment.
The Advanced Options dialog box appears.
p:<DOMAIN_NAME>\SAPService<SID>
where <DOMAIN_NAME> is the Windows domain that the user SAPService<SID> belongs to.
If the system HWA is running on account SAPServiceHWA of the MYDOMAIN domain, you enter:
p:MYDOMAIN\SAPServiceHWA
The SAP Logon window now displays an icon with a small yellow key beside the system entry. This indicates that SSO is active.
