Unable to login with CRAM-MD5 over TLS

[nailyk-fr]

My webserver and my dovecot are on two separate debian.
Dovecot only allow CRAM-MD5 login.

disable_plaintext_auth = yes
auth_mechanisms = CRAM-MD5

On the admin rainloop admin panel connection test is successful. When login-in on the user panel it fail every time.
The dovecot report:

Apr 30 14:38:24 imap-login: Info: Disconnected (tried to use unsupported auth mechanism): user=<>, method=PLAIN, rip=xxxx:xxxx:4ad5:2600:1::205, lip=xxxx:xxxx:4ad5:2600:1::201, TLS, session=

The rainloop log report:

When I enable plain in dovecot everything is going fine so I suppose the TLS configuration is ok.
I also try to set:

data/data/default/configs/application.ini:use_imap_auth_cram_md5 = On

in the lab section

Did I miss something?
Thank for your time.

P.S.: full rainloop log

Did I miss something?

No, RainLoop does not support CRAM-MD5 authentication (not ready yet :( ).

If you give me test email account, I will try to finish this functionality.

If you give me test email account, I will try to finish this functionality.

Sure! How can I contact you privately to send you the credentials?

Are changes needed in the rainloop configuration or something else i miss?
Are you still able to access the dovecot?
