autodiscover(4gx)

Name
autodiscover — AutoDiscover HTTP Service Protocol handler (responder)

Description

A client would make a HTTP request to the /Autodiscover/Autodiscover.xml endpoint, which is handled by the Gromox oxdisco component.

The Autodiscover response contains the home server name and protocol options (MAPI-RPC-HTTP, MAPIHTTP, IMAP, etc.). A client uses this to set up the mailbox with MAPI services (like ``MSEMS`` or ``INTERSTOR``) within a MAPI profile.

Configuration directives (gromox.cfg)
The following directives are recognized when they appear in /etc/gromox/gromox.cfg.

oxdisco_advertise_mh
    This setting controls whether the AutoDiscover response should include a EXHTTP Protocol section. Possible values: yes, no, not_old_mso, only_new_mso. The latter two values can be used to finely control emission in case of clients other than Outlook.
    Default: yes

oxdisco_advertise_rpch
    This setting controls whether the AutoDiscover response should include EXCH/EXPR Protocol sections. Possible values: yes, no, only_old_mso, not_new_mso. The latter two values can be used to finely control emission in case of clients other than Outlook.
    Default: yes

oxdisco_exonym
    Globally valid name pointing to a default mailbox server in the Gromox server forest. (Since AutoDiscover nodes are also mailbox nodes, the exonym should simply be: this server's hostname).
    Default: (inherited from http.cfg:host_id, which defaults to the system FQDN)

oxdisco_pretty_response
    A debugging knob to make the Autodiscovery handler emit indented XML responses.
    Default: no

oxdisco_request_logging
    Log AutoDiscover requests. This is independent of http.cfg:http_debug, and setting both would log requests twice.
    Default: no

oxdisco_response_logging
    Log AutoDiscover responses. This is independent of http.cfg:http_debug, and setting both would log responses twice.
    Default: no

oxdisco_validate_scndrequest
    When OL opens a non-default store (store of another user) or a public store, it may also make an AutoDiscover inquiry for the extra store. This setting controls whether the AutoDiscover handler should perform a permission check on non-default stores and possibly reject returning connection details. (Inquiry of public stores are always permitted.)
    Default: yes

x500_org_name
    Default: (unspecified)

Outlook notes
When Outlook is active, it is possible to Ctrl-MouseBtn3 (right click) on the status tray icon to call up a context menu, from which "Test Email Autoconfiguration..." can be selected to debug AutoDiscover requests and responses from the Windows side.

Exchange notes
In EXC, MH can be toggled on/off via an EAC Shell command: `Set-OrganizationConfig -MapiHttpEnable $false` (or $true).
