Setting Login Security Mode
Change login security options to set the security mode to either Integrated or Mixed.
Adding Network Login Names to syslogins
To add a login name for each Windows user accessing SAP ASE over a trusted connection, use sp_addlogin. Include any nondefault domain names and the correct mapping characters in the login name.
Assigning Roles
To assign roles or “default” permissions to Windows users or groups, use sp_grantlogin. Keep in mind that assigning permissions to Windows groups generally provides more flexibility than assigning permissions to individual users.
