.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
This method implements the client part of the \s-1GSSAPI\s0 \s-1SASL\s0 algorithm.
.PP
With a valid Kerberos 5 credentials cache (aka \s-1TGT\s0) it allows
to connect to \fIservice\fR@\fIhost\fR given as the first two parameters
to Authen::SASL's \fIclient_start()\fR method.
.PP
Please note that this module does not currently implement a \s-1SASL\s0
security layer following authentication. Unless the connection is
protected by other means, such as \s-1TLS\s0, it will be vulnerable to
man-in-the-middle attacks. If security layers are required, then the
Authen::SASL::Cyrus \s-1GSSAPI\s0 module should be used instead.
.Sh "\s-1CALLBACK\s0"
.IX Subsection "CALLBACK"
The callbacks used are:
.IP "user" 4
.IX Item "user"
The username to be used in the response
