            With the 
               		osesm security manager, users sign on to MFDSand/or Enterprise Server Administration using their Windows username and password. 
               	 
            
 
            	 
            Note: osesm only supports the 
               		Verify operation (user sign-on). It does not do any resource access control (the Auth and XAuth operations). To control access to
               resources for signed-on users, you will need to configure another ESM module lower in the list for that purpose. 
               	 
            
 
            	 
            By default 
               		osesm first tries to sign a user on locally. If that fails, it does a search in the default domain (in the domain forest, on Windows
               2003 and later) and tries again in the first domain where it finds the user. You can specify a different domain to try initially
               in the security manager configuration. 
               	 
            
 
            	 
            Note: osesm is limited to the signon IDs that Windows normally allows, and therefore it cannot verify a user in a domain that is not
               trusted by the local system. 
               		osesm can authenticate users from any domain that is listed in the Windows sign-on dialog. It cannot authenticate signons of the
               form 
               		username@domain.tld: the signon screens do not support this. 
               	 
            
 
            	 
            osesm supports ESF Passtokens, which can be used to automatically pass credentials between MFDS and the Enterprise Server administration
               UI, if both the directory server and Enterprise Server are configured to use 
               		osesm.
