[Alpine-info] Selectively disable authenticators?

[Neil Hoggarth]

Is there any way that I can disable a particular authenticator for 
connections to a particular server, whilst leaving that authenticator 
available for talking to other servers?

I find myself having to talk to an MS-Exchange IMAP service which 
advertises AUTH=GSSAPI, but for which Kerberos authentication doesn't 
actually work (Alpine error message "Kerberos failure: Server not found 
in Kerberos database for <fqdn of server>"). I can then authenticate to 
the server using a username and password, but everytime Alpine needs to 
make a fresh connection to the server in question the Kerberos failure 
message comes up again and there is a brief but annoying pause.

The recommended work around from the Exchange admins is to disable 
GSSAPI as an authenticator in Alpine using the 
disable-these-authenticators pinerc option. I would like to avoid 
globally disabling GSSAPI if I can, because it is successfully providing 
proper Kerberos single-sign-on capability to the SMTP server that I use, 
and a second IMAP server that I access.
