Tech Info: Unable to login: username and password are incorrect

why attempts to login into the IBM® Rational® ClearCase® Remote Client (CCRC) where the Rational Web Platform (RWP) is hosted on a Microsoft® Windows® 2003 Server results in the error Unable to login: username and password are incorrect.

Cause

Attempts to log into CCRC from a Windows client (such as XP) where the RWP server is hosted on Windows 2003 Server fails during authentication with the error:

ClearCase view tag: ccrc_view Unable to login: username and password are incorrect

Notes:

The user is logging in with a Domain User account.
Other users can log into this server.

The domain user does not have the right permission to authenticate on that particular Windows 2003 Server.

Solution

Follow the instructions in the ClearCase Administrator's Guide to configure the Rational Web Platform. Once you have verified that the RWP setup is OK, if no changes were made to your configuration, attempt the below steps.

Adjust the Local Security Policy on the Windows 2003 Server running RWP to allow the appropriate Domain User (or groups) access to log on locally.

1. Log on as an Administrator and click Start > Run type secpol.msc. The Local Security Settings windows will appear.

2. Navigate to Local Policies > User Rights Assignment > Allow log on locally

3. Double click the Log on locally item to view the properties and click Add User or Group... to add the required users or groups. Click OK on all windows to exit.
