If the the DC Directory Manager current password is unknown, it is possible to use the attached file to change the password to 'ciscocisco'. The file can be edited to change it to anything else. This works on CM 3.3
The following steps have to be done:
 
1. Copy the attached file to C:\dcdsrvr\run\dcx500\config directory (edit if desired with any other pwd name)
 
2. Run the following command from a DOS window: “cdsadmin chgpwd”
If succesful you will get an output which look like this:
Performing DSA-Administration (chgpwd)...
DSA-Administration succeeded - See C:\dcdsrvr\run\dcx500\config\chgpwd.txo
