         These functions can also fail if the name service switch does not
         specify valid project(4) name service sources. In the case of an
!        incompletely configurated name service switch configuration,
         getprojbyid() and other functions can return error values other than
         those documented above. These conditions usually occur when the
         nsswitch.conf file indicates that one or more name services is
         providing entries for the project database when that name service does
         not actually make a project table available.
