Summary: Dovecot authenticator documentation is incomplete
Product: Exim
Version: 4.82
Platform: All
OS/Version: All
Status: NEW
Severity: bug
Priority: medium
Component: Documentation
AssignedTo: nigel@???
ReportedBy: peter+exim@???
CC: exim-dev@???
My goal: configuring Exim to use Dovecot as authenticator.
Following the documentation[1], I should set the following:
dovecot_plain:
driver = dovecot
public_name = PLAIN
server_socket = /var/run/dovecot/auth-client
server_set_id = $auth2
I have not tried this since I have no idea what this magic $auth2 means.
Looking in the source code, it seems wrong too. In src/auths/dovecot.c, I see:
/*
* Search for the "user=$USER" string in the args array
* and return the proper value.
*/
for (i=2; (i<nargs) && (auth_id_pre == NULL); i++)
{
if ( Ustrncmp(args[i], US"user=", 5) == 0 )
{
auth_id_pre = args[i]+5;
expand_nstring[1] = auth_vars[0] =
string_copy(auth_id_pre); /* PH */
expand_nlength[1] = Ustrlen(auth_id_pre);
expand_nmax = 1;
}
}
This (auth_vars[0]) seems to set $auth1 to the username (which should be
documented!).
$auth2 seems to come from the SASL code where $auth1 means "AUTHID", $auth2
refers to "$AUTHZ" and $auth3 the password. This is however *not* applicable to
the dovecot documentation.
Please update the documentation, my quick analysis might be wrong so I would
like to have your feedback on it.
