Preparing to use security model B for RPCs

Table 14-7 provides steps for using security model B to establish security for RPCS.

**Table 14-7: Process for using security model B for RPCs**
Task, who performs it, and where	Command, system procedure, or tool	See
System Administrator from the operating system: 1. Make sure the interfaces file or the Directory Service contains an entry for both servers and a secmech line listing the security mechanism.	UNIX: dscp or dscp_dce Desktop: dsedit	“Specifying security information for the server” dscp or dscp_dce in the Open Client/Server Configuration Guide for UNIX. dsedit in the Open Client/Server Configuration Guide for Desktop Platforms.
System Security Officer on remote server: 2. Add the local server to master..sysservers.	sp_addserver Example: `sp_addserver "lcl_server"`	“Adding a remote server”. sp_addserver in the Reference Manual.
System Security Officer on remote server: 3. Add logins to master..syslogins.	sp_addlogin Example: `sp_addlogin user1, "pwuser1"`	“Adding logins to Adaptive Server”. sp_addlogin in the Reference Manual.
System Security Officer on remote server: 4. Set use security services on, and set the rpc security model B as the model for connections with the local server.	sp_configure – to set use security services sp_serveroption – to set the RPC security model Example: `sp_configure "use security services", 1sp_serveroption lcl_server, "rpc security model B", true`	“Establishing the security model for RPCs”. “Enabling network-based security”. use security services (Windows NT only) in Chapter 5, “Setting Configuration Parameters” in this manual. sp_configure and sp_serveroption in the Reference Manual.
System Administrator on remote server: 5. Optionally, specify certain users as “trusted” to log into the remote server from the local server without supplying a password.	sp_remoteoption Example: `sp_remoteoption lcl_server, user1, user1, trusted, true`	“Password checking for remote users”. sp_remoteoption in the Reference Manual.
System Security Officer on local server: 6. Add both the local server and the remote server to master..sysservers.	sp_addserver Example: `sp_addserver lcl_server, local sp_addserver rem_server`	“Adding a remote server”. sp_addserver in the Reference Manual.
System Security Officer on local server: 7. Add logins to master..logins.	sp_addlogin Example:`sp_addlogin user1, "pwuser1"`	“Adding logins to Adaptive Server”. sp_addlogin in the Reference Manual.
System Security Officer on local server: 8. Set use security services on, and set the rpc security model B as the model for connections with the remote server.	sp_configure – to set use security services sp_serveroption – to set the RPC security model Example: `sp_configure "use security services", 1 sp_serveroption rem_server, "rpc security model B", true`	“Establishing the security model for RPCs”. “Enabling network-based security”. use security services (Windows NT only) in Chapter 5, “Setting Configuration Parameters” in this manual. sp_configure and sp_serveroption in the Reference Manual.
System Security Officer on local server: 9. Specify the security mechanism and the security services to use for connections with the remote server.	sp_serveroption Example: `sp_serveroption rem_server, "security mechanism", dce sp_serveroption rem_server, "use message integrity", true`	“Setting server connection options”. sp_serveroption in the Reference Manual.
