Destruction usually involves deallocation of private data structures. The use of .Fa auth is undefined after calling .Fn auth_destroy . .Pp .Fn authnone_create creates and returns an RPC authentication handle that passes nonusable authentication information with each remote procedure call. This is the default authentication used by RPC. .Pp .Fn authunix_create creates and returns an RPC authentication handle that contains .Ux authentication information. The parameter .Fa host is the name of the machine on which the information was created; .Fa uid is the user's user ID; .Fa gid is the user's current group ID; .Fa len and .Fa aup_gids refer to a counted array of groups to which the user belongs. It is easy to impersonate a user. .Pp .Fn authunix_create_default calls .Fn authunix_create with the appropriate parameters. .Pp .Fn set_rpc_maxgrouplist allows the application to set the maximum size of the group list that will be used in .Fn authunix_create_default to .Fa num . Some servers will refuse mounts if the group list is larger than it expects (like 8). .Sh SEE ALSO .\"Xr rpc_secure 3 , .Xr rpcgen 1 , .Xr select 2 , .Xr getrpcport 3 , .Xr rpc 3 , .Xr xdr 3 , .Xr rpc 5 , .Xr portmap 8 .Rs .%T Remote Procedure Calls: Protocol Specification .Re .Rs .%T Remote Procedure Call Programming Guide .Re .Rs .%T rpcgen Programming Guide .Re .Sh STANDARDS .Rs .%D June 1988 .%Q Sun Microsystems, Inc. .%R RFC 1057 .%T RPC: Remote Procedure Call Protocol Specification Version 2 .Re
