pserver is an insecure protocol... authentication and data is sent plain.
Passwords could be very easily sniffed. Use only in a LAN where you trust
everybody and every host on your network.

sserver is more-or-less the same as pserver, except that the authentication
and data is sent over an SSL-secured channel.

With sspi the authentication credentials are done by exchanging SSPI tokens
and other such stuff... and is considered secure(ish) against password
sniffing... the data may or may not be encrypted.

gserver... same again, but using kerberos-based credentials.

In simple terms, if you clients are windows-based, stick to :sspi:,
otherwise use :sserver:.
