NAME

mech, qop —

GSS-API Mechanism and QOP files

SYNOPSIS

/etc/gss/mech /etc/gss/qop

DESCRIPTION

The /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:

Name: The name of this GSS-API mechanism.
Object identifier: The OID for this mechanism.
Library: A shared library containing the implementation of this mechanism.
Kernel module: Optional kernel module containing the implementation of this mechanism (not yet supported in FreeBSD).
Library options: Optional parameters interpreted by the mechanism. Library options must be enclosed in brackets ([ ]) to differentiate them from the optional kernel module entry.

The first mechanism listed in /etc/gss/mech is the default mechanism. This mechanism will be used by gss_init_sec_context(3) if the user doesn't specify a specific mechanism.

The /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:

QOP string: The name of this Quality of Protection algorithm.
QOP value: The numeric value used to select this algorithm for use with GSS-API functions such as gss_get_mic(3).
Mechanism name: The GSS-API mechanism name that corresponds to this algorithm.

EXAMPLES

This is a typical entry from /etc/gss/mech:

kerberosv5	1.2.840.113554.1.2.2	/usr/lib/libgssapi_krb5.so.8	-

This is a typical entry from /etc/gss/qop:

GSS_KRB5_CONF_C_QOP_DES		0x0100	kerberosv5
