The version of c-client your PHP installation is probably linked against kerberos. If your exchange server is advertising the ability to do kerberos authentication, c-client will try to use it. I believe that c-client will want to use the best authentication method available, and kerberos is far better than plaintext, cram/md5, etc.
Things to try.. - prevent the IMAP/POP server from advertising the ability to accept kerberos authentication - try rebuilding c-client w/o kerberos (you'll also need to rebuild the php imap extension, depending on how things are linked) Liam Games, Dax wrote: > Tried it.
