Default Domain

SAP ASE uses the default domain parameter to specify the Windows or LAN Manager domain name for matching network user names to SAP ASE login names.

Because two different domains can define the same network user name for two different users, the following rules apply:

SAP ASE can authorize access to both distinct users, but it must be able to distinguish between the two names in the login process for a trusted connection.
For user names defined in domains other than the parameter’s default value, SAP ASE adds the domain name and a domain separator, a backslash character (\), to the network user name before looking for the user name in the syslogins table.
For example, the domain MARKETING is the SAP ASE default definition, and two different users employ the network user name “john”, one in the MARKETING domain and the other in the ENGINEERING domain.
- John in MARKETING accesses SAP ASE with the login name of “john” over a trusted connection.
- John in ENGINEERING accesses the same SAP ASE with a login name of “ENGINEERING\john” to which his name was mapped before the software looked it up in syslogins.
When your server computer participates in a specific domain, set the default domain parameter to that domain name. Otherwise, set default domain to the server’s computer name.
