14 The gssproxy proxymech module is a interposer plugin that is loaded by
15 GSSAPI. It is enabled by /etc/gss/mech configuration file.
16
17 The interposer plugin allows to intercept the entire GSSAPI
18 communication and detour to the gssproxy daemon. When the interposer
19 plugin is installed two other conditions need to be met in order to
20 activate it:
21
22 a) interposer configuration file
23 The plugin needs to be manually enabled in the /etc/gss/mech file.
24
25 b) gssproxy environment variable
26 With default build options the interposer plugin will not forward
27 to the gssproxy daemon unless the environment variable named
28 GSS_USE_PROXY=yes is set.
29
30 This behavior default may be controlled at build time and can be
31 set to always forward unless the environment variable is set to
32 GSS_USE_PROXY=no
33
34 The current setting for always forwarding is: false
35
36 Furthermore, the interposer plugin can be configured to behave in
37 different ways when called from the GSSAPI. This behavior is controlled
38 via the GSSPROXY_BEHAVIOR environment variable. It accepts four
39 different values:
40
41 LOCAL_ONLY
42 All commands received with this setting will cause to immediately
43 reenter the GSSAPI w/o any interaction with the gssproxy daemon.
44 When the request cannot be processed it will just fail.
45
46 LOCAL_FIRST
47 All commands received with this setting will cause to immediately
48 reenter the GSSAPI. When the local GSSAPI cannot process the
49 request, it will resend the request to the gssproxy daemon.
50
51 REMOTE_FIRST
52 All commands received with this setting will be forwarded to the
53 gssproxy daemon first. If the request cannot be handled there, the
54 request will reenter the local GSSAPI.
55
56 REMOTE_ONLY
57 This setting is currently not fully implemented and therefor not
58 supported.
59
60 The default setting for GSSPROXY_BEHAVIOR is REMOTE_FIRST.
61
62 Finally the interposer may need to use a special per-service socket in
63 order to communicate with gssproxy. The path to this socket is set via
64 the GSSPROXY_SOCKET environment variable.
65
67 gssproxy.conf(5) and gssproxy(8).
