.Nd "GSS-API Mechanism and QOP files"
.Sh SYNOPSIS
.Pa "/etc/gss/mech"
.Pa "/etc/gss/qop"
.Sh DESCRIPTION
The
.Pa "/etc/gss/mech"
file contains a list of installed GSS-API security mechanisms.
Each line of the file either contains a comment if the first character
is '#' or it contains five fields with the following meanings:
.Bl -tag
.It Name
The name of this GSS-API mechanism.
.It Object identifier
The OID for this mechanism.
.It Library
A shared library containing the implementation of this mechanism.
.It Kernel module (optional)
A kernel module containing the implementation of this mechanism (not
yet supported in FreeBSD).
.It Library options (optional)
Optional parameters interpreted by the mechanism. Library options
must be enclosed in brackets ([ ]) to differentiate them from the
optional kernel module entry.
.El
.Pp
The first mechanism listed in
.Pa "/etc/gss/mech"
is the default mechanism.
This mechanism will be used by
.Xr gss_init_sec_context 3
if the user doesn't specify a specific mechanism.
.Pp
The
.Pa "/etc/gss/qop"
file contains a list of Quality of Protection values for use with
GSS-API.
Each line of the file either contains a comment if the first character
is '#' or it contains three fields with the following meanings:
.Bl -tag
.It QOP string
The name of this Quality of Protection algorithm.
.It QOP value
The numeric value used to select this algorithm for use with GSS-API
functions such as
.Xr gss_get_mic 3 .
.It Mechanism name
The GSS-API mechanism name that corresponds to this algorithm.
