HI,

I am in the process of setting up a new Maia system (FINALLY) to replace
my old 1.0.2{something} system running on a different machine.  I've
started from scratch, with a fresh maia database.  That all is working
great.  But now I'm trying to convert authentication from internal to imap
(which is how I had it configured on the old system).

I installed php-pear-Net-IMAP and php-imap.
The configtest.php says PEAR::Net_IMAP and IMAP library are both "OK".
I have the same username as I did on the old system.
I am PRETTY sure I have IMAP set up the same as I did on the old system.
I can log into squirrelmail on the new system, so I know IMAP *can*
authenticate (and that I know the password).
However, when I change config.php to say $auth_method = "imap"; I can no
longer login to maia.

A few things to note:  on Maia I always use <user>@<domain> to login.  On
Squirrelmail I use <user>.  This is the same <user>.   This worked on the
old server, but isn't working now.

From the logs, I can see that there is a connection to IMAP, but I can't
see anything beyond that.  I don't see an error message or even a login
attempt failure.  The maillog logs just say:

Jan 30 16:08:48 mail cyrus/imap[14657]: inittls: Loading hard-coded DH
parameters
Jan 30 16:08:48 mail cyrus/imap[14657]: starttls: TLSv1.3 with cipher
TLS_AES_256_GCM_SHA384 (256/256 bits new) no authentication

When I login via squirrelmail I then get:

Jan 30 15:25:41 mail cyrus/imaps[804]: login: <HOST> [X.X.X.X] <user>
plaintext+TLS User logged in SESSIONID=<cyrus-804-1612038341-1-....>

I don't see anything like this from maia.  And after the page "times out"
I have an empty "xlogin.php" screen.

If I change the imap host and port to ssl://<hostname> and port 993, then
I get xlogin.php that says:

Login for user <user> failed.
( not connected! (CMD:LOGIN) )
[ Try again ] , or contact <admin> for assistance.

This happens regardless of whether I set it up to talk to the new IMAP
server OR the old IMAP server....

What do I need to do to debug this and get it working?
