PHP ImapBy Eric Antoine Scuccimarra
If you get an error trying to connect with php_imap for Kerberos:
PHP Notice: Unknown: Kerberos error: No credentials cache found (try running kinit) for imap.example.com (errflg=1) in Unknown on line 0
This is the solution:
Pass ['DISABLE_AUTHENTICATOR' => 'GSSAPI'] to imap_open for the last options parameter.
