NAME

       client.conf - client configuration file for cups (deprecated)

DESCRIPTION

       The  client.conf  file configures the CUPS client and is normally located in the /etc/cups and/or ~/.cups
       directories.  Each line in the file can be a configuration directive, a blank line, or a comment. Comment
       lines start with the # character.

       Note: Starting with OS X 10.7, this file is only used by command-line and X11 applications plus  the  IPP
       backend.  The ServerName directive is not supported on OS X at all.

   DIRECTIVES
       The following directives are understood by the client. Consult the online help for detailed descriptions:

       AllowAnyRoot Yes

       AllowAnyRoot No
            Specifies  whether to allow TLS with certificates that have not been signed by a trusted Certificate
            Authority.  The default is "Yes".

       AllowExpiredCerts Yes

       AllowExpiredCerts No
            Specifies whether to allow TLS with expired certificates.  The default is "Yes".

       Encryption IfRequested

       Encryption Never

       Encryption Required
            Specifies the level of encryption that should be used.

       GSSServiceName name
            Specifies the Kerberos service name that is used for authentication, typically  "host",  "http",  or
            "ipp".   CUPS  adds  the  remote  hostname  ("name@server.example.com") for you. The default name is
            "http".

       ServerName hostname-or-ip-address[:port]

       ServerName /domain/socket
            Specifies the address and optionally the port to use when connecting  to  the  server.   Note:  This
            directive it not supported on OS X 10.7 or later.

       ServerName hostname-or-ip-address[:port]/version=1.1
            Specifies the address and optionally the port to use when connecting to a server running CUPS 1.3.12
            and earlier.

       SSLOptions [AllowDH] [AllowRC4] [AllowSSL3] [DenyTLS1.0]

       SSLOptions None
            Sets  encryption options (only in /etc/cups/client.conf).  By default, CUPS only supports encryption
            using TLS v1.0 or higher using known secure cipher suites.  The AllowDH option enables cipher suites
            using plain Diffie-Hellman key negotiation.  The AllowRC4 option  enables  the  128-bit  RC4  cipher
            suites,  which  are required for some older clients that do not implement newer ones.  The AllowSSL3
            option enables SSL v3.0, which is required for some older clients that do not support TLS v1.0.  The
            DenyTLS1.0 option disables TLS v1.0 support - this sets the minimum protocol version to TLS v1.1.

       User name
            Specifies the default user name to use for requests.

       ValidateCerts Yes

       ValidateCerts No
            Specifies whether to only allow TLS with certificates whose common name matches the  hostname.   The
            default is "No".

NOTES

       The client.conf file is deprecated and will no longer be supported in a future version of CUPS.
