You can enable Bentley IMS authentication either during datasource creation (through the New Datasource Wizard) or after the datasource is created (by manually editing the DMSKRNL.CFG file).

To enable Bentley IMS authentication during datasource creation, turn on the Support Bentley IMS authentication option on the New Datasource Wizard:

To enable Bentley IMS authentication after the datasource is created, open the DMSKRNL.CFG file on the ProjectWise Design Integration Server computer (...\ProjectWise\bin) and add the line STS=1 to the end of the section containing settings specific to that datasource (starting with [db0], [db1], and so on).

For example:

[db0]
Description=pwtest
Type=Microsoft SQL Server
DisplayName=pwtest
InterfaceType=ODBC
Name=pwdb
DBUserName=pwadmin
DBUsrPwdDecrypt=5
DBUserPassword=<encryptedpassword>
STS=1

Before the introduction of Bentley IMS authentication, the SSO=1 setting was only used to enable Windows single sign-on. Now that Bentley IMS authentication exists, the SSO=1 setting is used in conjunction with the STS=1 setting to enable Bentley IMS single sign-on for the datasource:

• When SSO=0 and STS=0 (or neither setting is present), then Windows single sign-on is disabled, and Bentley IMS authentication is also disabled.
• When SSO=1 and STS=0, then Windows single sign-on is enabled, and Bentley IMS authentication is disabled.
• When SSO=0 and STS=1, then Windows single sign-on is disabled, and Bentley IMS authentication (without single sign-on) is enabled.
• When SSO=1 and STS=1, then Windows single sign-on is enabled, and Bentley IMS authentication (with single sign-on) is also enabled.

[db0]
Description=pwtest
Type=Microsoft SQL Server
DisplayName=pwtest
InterfaceType=ODBC
Name=pwdb
DBUserName=pwadmin
DBUsrPwdDecrypt=5
DBUserPassword=<encryptedpassword>
SSO=1
STS=1

In the example datasource configuration above, both Windows single-sign on and Bentley IMS authentication (with single sign-on) are enabled.
