Quick update for future Google sanity --

My hosts were all deployed from VMware templates, and had registered an invalid 
client name in nsrladb.  After we deleted /nsr/res/nsrladb directory from all 
clients where authentication (whether for NMM or NMC purposes) was periodically 
or continuously failing, both NMM and NMC function correctly.
