To add a login name for each NT user who will access Adaptive Server over a trusted connection, use sp_addlogin. Include any nondefault domain names and the correct mapping characters in the login name.
If you are not sure what to enter as the login name, experiment with a sample user to clarify your options:
Use sp_grantlogin to assign a role to a sample user on the network.
Enter sp_logininfo to determine what the format of entries in syslogins should look like.
Use the entries listed in the mapped login name column as templates for the login names you create with sp_addlogin.
