Re: Bug #12883 Updated: krb4 support in c-client

If you guys decide not to commit the patch (which I can understand given the unsupported nature of krb4 in c-client, and the apache server module of PHP inability to use it properly)... Would you consider putting an entry in the FAQ about the "auth_link(&auth_krb);" line in php_imap.c? It took me months to track that down. thanks Quoting Bug Database <php-dev@lists.php.net>: > ID: 12883 > Updated by: sniper > Reported By: liamr@umich.edu > Old Status: Open > Status: Analyzed > Bug Type: Feature/Change Request > Operating System: Solaris (SPARC) 2.6 > PHP Version: 4.0CVS-2001-08-21 > New Comment: > > Before anybody commits this patch here's a note from IMAP > docs/FAQ: > ---------------------------------------------------------- > Q: Can I use Kerberos V4? > A: Kerberos V4 is not supported.
