Brave folk can contact the author. 56 57.Nm /etc/passwd 58and 59.Nm /etc/group only supports "+" entries. 60 61Many more manual pages should be written, especially ypclnt(3). 62For the time being, seek out a local Sun machine and read the 63manuals for there. 64 65Neither Sun nor this author have found a clean way to handle 66the problems that occur when ypbind cannot find its server 67upon bootup. 68.Sh HISTORY 69The 70.Nm YP 71subsystem was written from the ground up by Theo de Raadt 72to be compatible to Sun's implimentation. No Sun code was 73referenced. 74
