When Windows single sign-on is enabled for a datasource, a user who has a Windows domain account in a datasource, and is currently logged in to the operating system as that user, can double-click a datasource in ProjectWise Explorer and be automatically logged in without being prompted to enter their a user name and password.

Windows single sign-on is disabled by default for all datasources on a server. To enable single sign-on for a particular datasource, open the DMSKRNL.CFG file (C:\Program Files\Bentley\ProjectWise\bin) and add the line SSO=1 to the end of the section containing settings specific to that datasource. For example:

[db0]
Description=exton-tbb-0822
DisplayName=exton-tbb-0822
Type=Microsoft SQL Server
InterfaceType=ODBC
Name=exton-tbb-0822
DBUserName=pwadmin
DBUserPassword=000544d20001556b0000a432
DBUsrPwdDecrypt=1
SSO=1

To disable single sign-on once its enabled, you can either change SSO=1 to SSO=0, or you can delete the line entirely.
