Thunderbird:Supported authentication methods
Kerberos
Mozilla 1.7 has support for GSSAPI authentication for HTTP, and thus supports kerberos. It would be good to have GSSAPI auth for IMAP (and LDAP) in TB. Is the support there? What needs to be developed and tested? I'll try to gather relevant bugs and references to source code here.
IMAP
TB supports IMAP authentication, though I'm not sure which hashing schemes it supports of MD5, crypt, etc.
SMTP
I guess this is similar to IMAP auth.
POP3
I don't use this old protocol.
NTLM?
This is not listed as an available authentication method in the UI.
