I've been using a similar style of printing authentication for some
time with my own patches, currently to netatalk-971027 on solaris. My
implementation makes afpd create a file whose name is the net.node and
content is the username, and creates an advisory lock on it. papd then
tries to open the appropriate file and lock it - if the lock fails it
means there is an afpd session from that net.node and the username in
the file is valid. Rather than looking in a single directory for the
auth files papd enumurates a directory of directories. This enables a
printer server host to NFS mount the auth directories of other afpd
server hosts so a user can print if he is authenticated by one of
several hosts running afpd - the patches and brief instructions are in
ftp://ftp.ncl.ac.uk:/pub/users/ngmt/netatalk.
