NMAS is defined as a core service after it is installed because other services (such as eDirectory) might auto-integrate to use NMAS features. Because of these dependencies, it is not possible to fully uninstall this release of NMAS. However, you can disable NMAS on a server-by-server basis by performing the following steps:
Stop the eDirectory service.
Rename the nmas.dlm file.
Restart the eDirectory service.
Stop the eDirectory service.
Rename the libnmas.so file.
Restart the eDirectory service.
