78For example,
79.Dq Li passwd
80supports a numeric UID or user name;
81.Dq Li hosts
82supports an IPv4 address, IPv6 address, or host name;
83and
84.Dq Li services

96The
97.Nm
98utility exits 0 on success,
991 if there was an error in the command syntax,
1002 if one of the specified key names was not found in
101.Ar database ,
102or 3 if there is no support for enumeration on
