For the Lotus Notes driver for Identity Manager, one of the tasks to be performed is to copy the dsrepcfg.ntf file to the \lotus\domino\data directory.
However, the installer leaves the file set as Read Only, when it is done, as it copies from the CD.
Remember to remove the RO (read-only) flag, or else you will not be able to digitally sign the file. You need to do this so that the Lotus Domino server will allow it to be used.
