    # Initiates a connection to "server" on "port"
    # or to the unix "socket" on the local machine
    # and authenticates with "user" and "password".
    # Failed connections will be retried for
    # "tries" times, waiting "retrytime" seconds
    # between each try.  If "tries" is 0 then retries
    # will continue forever.  If "retrytime" is 0 then
    # retries will be attempted on a default interval.
    #
    # If the "socket" parameter is neither
    # NULL nor "" then an attempt will be made to
    # connect through it before attempting to
    # connect to "server" on "port".  If it is
    # NULL or "" then no attempt will be made to
    # connect through the socket.

    # Enables Kerberos authentication and encryption.
    #
    # "service" indicates the Kerberos service name of the
    # SQL Relay server.  If left empty or NULL then the service
    # name "sqlrelay" will be used. "sqlrelay" is the default
    # service name of the SQL Relay server.  Note that on Windows
    # platforms the service name must be fully qualified,
    # including the host and realm name.  For example:
    # "sqlrelay/sqlrserver.firstworks.com@AD.FIRSTWORKS.COM".
    #
    # "mech" indicates the specific Kerberos mechanism to use.
    # On Linux/Unix platforms, this should be a string
    # representation of the mechnaism's OID, such as:
    #     { 1 2 840 113554 1 2 2 }
    # On Windows platforms, this should be a string like:
    #     Kerberos
    # If left empty or NULL then the default mechanism will be
    # used.  Only set this if you know that you have a good
    # reason to.
    #
    # "flags" indicates what Kerberos flags to use.  Multiple
    # flags may be specified, separated by commas.  If left
    # empty or NULL then a defalt set of flags will be used.
    # Only set this if you know that you have a good reason to.
    #
    # Valid flags include:
    #  * GSS_C_MUTUAL_FLAG
    #  * GSS_C_REPLAY_FLAG
    #  * GSS_C_SEQUENCE_FLAG
    #  * GSS_C_CONF_FLAG
    #  * GSS_C_INTEG_FLAG
    #
    # For a full list of flags, consult the GSSAPI documentation,
    # though note that only the flags listed above are supported
    # on Windows. */
    proc enableKerberos {service mech flags}

    # Enables TLS/SSL encryption, and optionally authentication.
    #
    # "version" specifies the TLS/SSL protocol version that the
    # client will attempt to use.  Valid values include SSL2,
    # SSL3, TLS1, TLS1.1, TLS1.2 or any more recent version of
    # TLS, as supported by and enabled in the underlying TLS/SSL
    # library.  If left blank or empty then the highest supported
    # version will be negotiated.
    #
    # "cert" is the file name of the certificate chain file to
    # send to the SQL Relay server.  This is only necessary if
    # the SQL Relay server is configured to authenticate and
    # authorize clients by certificate.
    #
    # If "cert" contains a password-protected private key, then
    # "password" may be supplied to access it.  If the private
    # key is not password-protected, then this argument is
    # ignored, and may be left empty or NULL.
    #
    # "ciphers" is a list of ciphers to allow.  Ciphers may be
    # separated by spaces, commas, or colons.  If "ciphers" is
    # empty or NULL then a default set is used.  Only set this if
    # you know that you have a good reason to.
    #
    # For a list of valid ciphers on Linux/Unix platforms, see:
    #     man ciphers
    #
    # For a list of valid ciphers on Windows platforms, see:
    #     https://msdn.microsoft.com/en-us/library/windows/desktop/aa375549%28v=vs.85%29.aspx
    # On Windows platforms, the ciphers (alg_id's) should omit
    # CALG_ and may be given with underscores or dashes.
    # For example: 3DES_112
    #
    # "validate" indicates whether to validate the SQL Relay's
    # server certificate, and may be set to one of the following:
    #     "no" - Don't validate the server's certificate.
    #     "ca" - Validate that the server's certificate was
    #            signed by a trusted certificate authority.
    #     "ca+host" - Perform "ca" validation and also validate
    #            that one of the subject altenate names (or the
    #            common name if no SANs are present) in the
    #            certificate matches the host parameter.
    #            (Falls back to "ca" validation when a unix
    #            socket is used.)
    #     "ca+domain" - Perform "ca" validation and also validate
    #            that the domain name of one of the subject
    #            alternate names (or the common name if no SANs
    #            are present) in the certificate matches the
    #            domain name of the host parameter.  (Falls back
    #            to "ca" validation when a unix socket is used.)
    #
    # "ca" is the location of a certificate authority file to
    # use, in addition to the system's root certificates, when
    # validating the SQL Relay server's certificate.  This is
    # useful if the SQL Relay server's certificate is self-signed.
    #
    # On Windows, "ca" must be a file name.
    #
    # On non-Windows systems, "ca" can be either a file or
    # directory name.  If it is a directory name, then all
    # certificate authority files found in that directory will be
    # used.  If it a file name, then only that file will be used.
    #
    #
    # Note that the supported "cert" and "ca" file formats may
    # vary between platforms.  A variety of file formats are
    # generally supported on Linux/Unix platfoms (.pem, .pfx,
    # etc.) but only the .pfx format is currently supported on
    # Windows. */
