The imap_open() function documentation displays using the authuser swich, to authenticate as the superuser but act as another user.  This option fails against Cyrus IMAP servers, even though the underlying c-client supports it.  For example:
mailutil check {servername/imap/tls/novalidate-cert/authuser="cyrus"/user="uname"}INBOX

works, but the imap_open() call to do the same thing does not.

Reproduce code:
$mbox = imap_open('{servername/imap/tls/novalidate-cert/authuser="cyrus"/user="uname"}INBOX', "cyrus","cyruspw");

Expected result:
$mbox will be a valid imap mailbox stream.

Actual result:
Nothing, then in the error log:
[client ip.ip.ip.ip] PHP Warning:  imap_open(): Couldn't open stream {mailserver/imap/tls/novalidate-cert/authuser="cyrus"/user="uname"}INBOX in /var/www/html/cyrustt/testimap.php on line 3

[client ip.ip.ip.ip] PHP Notice:  (null)(): Can't do /authuser with this server (errflg=2) in Unknown on line 0

This is certainly a PHP bug, in the interface between php_imap and c-client.  The displayed error message 'can't do authuser with this server' is incorrect, we use the mailutil program, which does authuser, with this server.

Has this been resolved yet? I have to agree with ed2019 that this is certainly a PHP bug because the mailutil works fine from the command line.
