IMAP login Problem after upgrade to v1.2

[quwax]

Hello,
after upgrading to v1.2 I get an login error that the Krb5 modul is necessary for login with imap, although I changed in the config file the login method to CRAM-MD5. After that I installed Authen::Krb5 via CPAN on that machine, but it still doesn't seam to work.
On trying to login I get a message - connection to "Speicherserver" failed - probably to IMAP server.
When I run Test IMAP config from the installer I get:
IMAP connect:  NOT OK(Login failed for ..... The krb5 extension is required for GSSAPI authentication)
in the config.inc.php I set:
$config['imap_auth_type'] = CRAM-MD5;
Dovecot is set to Kerberos, CRAM-MD5, Login.

when I set $config['imap_auth_type'] = LOGIN;
it works.
So what's wrong with CRAM-MD5?
I'm not surprised that kerberos is not really working under 10.6
cheers

The box this is running on is a MacOS 10.6.8 Server with Dovecot and Postfix

This is a string and need to be quoted. So, 'CRAM-MD5' not CRAM-MD5.

Alec,
thanks, that works 
Just wondering why the default setting of nul is not working anymore (it did until v1.1).
cheers

1.1 did not support GSSAPI, so the capability was just ignored and CRAM-MD5 selected as a default. In 1.2 we have code for GSSAPI and as you noticed it requires some php module and additional configuration.
