The GNU SASL library does not have any required external dependencies,
but some optional features are enabled if you have a specific external
- The NTLM mechanism requires the library LibNTLM,
- The GSSAPI and GS2-KRB5 mechanisms requires a GSS-API library, see GNU
GSS (http://www.gnu.org/software/gss/). MIT Kerberos or Heimdal
are also supported.
- Processing of non-ASCII usernames and passwords requires the SASLprep
implementation in LibIDN (http://www.gnu.org/software/libidn/).
This is needed for full conformance with the latest SASL protocol
drafts, but is optional in the library for improved portability.
- The GNU SASL library ships with its own cryptographic implementation,
but it can use the one in libgcrypt (http://www.gnupg.org/)
instead, if it is available. This is typically useful for desktop
machines which have libgcrypt installed.
The command-line interface to GNU SASL requires a POSIX or Windows
platform for network connectivity. The command-line tool can make use
of GnuTLS (http://www.gnutls.org/) to support the STARTTLS modes
of IMAP and SMTP, but GnuTLS is not required.
Note that the library does not need a POSIX platform or network
