.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
