# idmapd - NFSv4 id <-> name mapper

# rpc.idmapd is the NFSv4 ID <-> name mapping daemon.  It provides
# functionality to the NFSv4 kernel client and server, to which it
# communicates via upcalls, by translating user and group IDs to names, and
# vice versa.

# This is modified from Ubuntu's idmapd.conf
