Because Account Management's name service switch provider, nss_nam, relies on the namcd daemon to query eDirectory, ensure that the namcd daemon is up and running.

If the /etc/nam.conf file is changed, namcd should be stopped and restarted.

namcd gets values from eDirectory, depending on the frequency specified for the cache-refresh period. If changes are made to existing User, Group, Linux Config, and Linux Workstation objects, namcd gets the values only after the interval specified for the cache-refresh period. Setting large values for this parameter increases cache hit rates and reduces mean response time, but increases problems with cache coherence.
