Implementation of NTLM (aka "Secure Password Authentication") auth, taken
* camel-sasl-ntlm.c: Implementation of NTLM (aka "Secure Password Authentication") auth, taken from soup. * Makefile.am (libcamel_la_SOURCES, libcamel_la_HEADERS): Add camel-sasl-ntlm. * camel-sasl.c: Add refs to camel-sasl-ntlm. * providers/imap/camel-imap-store.c (try_auth): Use imap_next_word() to skip over the "+ " of the continuation rather than just "resp + 2" since Exchange (incorrectly) returns "+" instead of "+ " for an empty continuation response. svn path=/trunk/; revision=15605
