Changing Multiple Device Manager user names and passwords Performing mdm configuration tasks

You can follow these procedures to change user names and passwords for MDM authentication.

MDM does not directly manage users. However, when you make changes to user names or passwords for either the MDM user ID, DB2, or Tivoli Storage Area Network Manager, you will also need to reflect these changes within MDM for successful authentication.

Note:Note: Only users who have administrator privileges can perform this task.

The MDM superuser and the DB2 user are managed by the operating system. Tivoli Storage Area Network Manager manages its own users.

Steps

Changing MDM user information: The MDM user ID specified in the 'MDM user information' section of the Configure MDM panel must be a valid operating system user ID, which means it must be in the DirSuper and DirAdmin groups.

  1. Changing the MDM user ID
    1. Create a new MDM user on the associated operating system (Microsoft Windows or Linux).
    2. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. You will make changes in the MDM user information section of this panel.
    3. In the User name field, change the user name to match the new name entered on the operating system in step 1a.
    4. Type the password in the Password field. (This password must be the same one specified for the associated user on the operating system.)
    5. Type the password again in the Confirm password field.
    6. Click OK.
  2. Changing the MDM user password
    1. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. You will make changes in the MDM user information section of this panel.
    2. Change the MDM user password on the operating system (Microsoft Windows or Linux).
    3. In the Password field, change the password to match the new password entered on the operating system in step 2b.
    4. Type the password again in the Confirm password field.
    5. Click OK.
  3. Procedure to recover when the MDM user names or passwords are not in synch between the operating system and MDM.
    1. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. Only the MDM user information is displayed because the other information cannot be retrieved at this point. You will make changes in the MDM user information section of this panel.
    2. In the User name field, change the user name to match the name entered on the operating system.
    3. In the Password field, change the password to match the password on the operating system.
    4. Type the password again in the Confirm password field.
    5. Click OK.
    6. If opened again, the remaining information on the Configure MDM panel should display.

Changing DB2 user information in MDM: The DB2 user ID specified in the 'DB2 information' section of the Configure MDM panel must be a valid operating system user ID. A few extra steps are needed for this procedure because the DB2 user information is also stored in WebSphere Application Server as 'alias.'

  1. Changing the DB2 user ID
    1. Create a new DB2 user on the associated operating system (Microsoft Windows or Linux).
      Notes:
      Notes:
      1. The DB2 user needs to be defined as a system user with system administrator privileges. To assign these privileges in Windows, the DB2 user must be in the Administrators group; on Linux the user must be in a group with SYSADM privileges, which is typically db2grp1.
      2. The DB2 user is also mapped to the MDM WebSphere Application Server JMS role.
    2. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. You will make changes in the DB2 information section of this panel.
    3. In the DB2 user name field, change the user name to match the new name entered on the operating system in step 1a.
    4. Type the password in the DB2 password field. (This password should be the same one specified for the associated user on the operating system.)
    5. Type the password again in the Confirm password field.
    6. Click OK. This action will propagate the new user ID to the mdm.properties file and it will be set for WebSphere Application Server, but not yet used.
    7. Restart WebSphere Application Server for the new settings to become effective.
  2. Changing the DB2 user password
    1. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. You will make changes in the DB2 information section of this panel.
    2. In the DB2 password field, change the password.
    3. Type the password again in the Confirm password field.
    4. Click OK.
    5. Stop WebSphere Application Server.
    6. Change the DB2 user password on the operating system (Microsoft Windows or Linux) to match the password you entered in step 2b.
    7. Restart WebSphere Application Server for the new settings to become effective.
  3. Procedure to recover when the DB2 user names or passwords are not in synch between the operating system and MDM.
    1. Open the WebSphere Application Server administrative console.
    2. From the left side of the panel, click Security --> JAAS Configuration --> J2C Authentication Data.
    3. Select DMCoservAlias.
    4. Type a user name and password to match what is specified in MDM.
    5. Click OK.
    6. The following message appears: "Changes have been made to your local configuration. Click Save to apply changes to master configuration." Save the new server configuration by clicking Save.
    7. Another panel displays on which you need to click Save again.
    8. Stop WebSphere Application Server.
    9. Restart WebSphere Application Server.
    10. Open the MDM configuration panel by clicking the IBM Director Task pane --> Multiple Device Manager --> Configure MDM. You will make changes in the DB2 information section of this panel.
    11. In the DB2 user name field, change the user name to match the name entered on the operating system and in WebSphere Application Server.
    12. In the Password field, change the password to match the password on the operating system and in WebSphere Application Server.
    13. Type the password again in the Confirm password field.
    14. Click OK. All DB2 settings should now be in synch.

Changing the Tivoli Storage Area Network Manager user information: The Tivoli Storage Area Network Manager user information specified in the 'TSANM information' section of the Configure MDM panel must match the password that was entered during Tivoli SAN Manager installation. You can only change this password during the Tivoli SAN Manager installation process.
