Unified logon

KCM Designer for Windows prompts the user to enter a name and password when starting. Optionally, the user may enter a Microsoft Windows account user name to log in to KCM Repository. This unified logon is performed automatically when KCM Designer for Windows is started. A verification is performed to ensure that the user name on the client is mapped to the same account on the server.

You cannot use unified logon when the LDAP mode is enabled in KCM Designer. For more information on LDAP, see User authentication in LDAP mode in this guide and the "User authorization" topic in KCM Designer Help.

To use unified logon:

Make sure the user accounts are created in KCM Repository with the names matching Windows user accounts.
Configure KCM Repository Server to allow unified logon. To do so:
1. Locate the itprep.ini file on the KCM server instance at: <deploy root>\KCM\Work\<version>\Instance_<num>\designer\Config
2. Open the file for editing and add the following line:
```
[Configuration] AllowUnifiedLogon=Y
```

When KCM Repository Server is configured to use unified logon, you can force KCM Designer for Windows to prompt the user to log in. For that, do any of the following:

Start KCM Designer for Windows with the /asklogin flag.
Add the following line to the itprep.ini file of the KCM Repository clients:
```
[Configuration] Asklogin=Y
```

If you are already logged in to KCM Designer for Windows, click File > Switch user to switch to another user.

If you switch to another user, your rights also change.
