+=head1 NAME
+
+SSL_CTX_set_client_CA_list, SSL_set_client_CA_list, SSL_CTX_add_client_CA,
+SSL_add_client_CA - set list of CAs sent to the client when requesting a
+client certificate
+
+=head1 SYNOPSIS
+
+ #include <openssl/ssl.h>
+
+ void SSL_CTX_set_client_CA_list(SSL_CTX *ctx, STACK_OF(X509_NAME) *list);
+ void SSL_set_client_CA_list(SSL *s, STACK_OF(X509_NAME) *list);
+ int SSL_CTX_add_client_CA(SSL_CTX *ctx, X509 *cacert);
+ int SSL_add_client_CA(SSL *ssl, X509 *cacert);
+
+=head1 DESCRIPTION
+
+SSL_CTX_set_client_CA_list() sets the B<list> of CAs sent to the client when
+requesting a client certificate for B<ctx>.
+
+SSL_set_client_CA_list() sets the B<list> of CAs sent to the client when
+requesting a client certificate for the chosen B<ssl>, overriding the
+setting valid for B<ssl>'s SSL_CTX object.
+
+SSL_CTX_add_client_CA() adds the CA name extracted from B<cacert> to the
+list of CAs sent to the client when requesting a client certificate for
+B<ctx>.
+
+SSL_add_client_CA() adds the CA name extracted from B<cacert> to the
+list of CAs sent to the client when requesting a client certificate for
+the chosen B<ssl>, overriding the setting valid for B<ssl>'s SSL_CTX object.
+
+=head1 NOTES
+
+When a TLS/SSL server requests a client certificate (see
+B<SSL_CTX_set_verify(3)>), it sends a list of CAs, for which
+it will accept certificates, to the client.
+
+This list must explicitly be set using SSL_CTX_set_client_CA_list() for
+B<ctx> and SSL_set_client_CA_list() for the specific B<ssl>. The list
+specified overrides the previous setting. The CAs listed do not become
+trusted (B<list> only contains the names, not the complete certificates); use
+L<SSL_CTX_load_verify_locations(3)>
+to additionally load them for verification.
+
+If the list of acceptable CAs is compiled in a file, the
+L<SSL_load_client_CA_file(3)>
+function can be used to help importing the necessary data.
+
+SSL_CTX_add_client_CA() and SSL_add_client_CA() can be used to add additional
+items the list of client CAs. If no list was specified before using
+SSL_CTX_set_client_CA_list() or SSL_set_client_CA_list(), a new client
+CA list for B<ctx> or B<ssl> (as appropriate) is opened.
+
+These functions are only useful for TLS/SSL servers.
+
+=head1 RETURN VALUES
+
+SSL_CTX_set_client_CA_list() and SSL_set_client_CA_list() do not return
+diagnostic information.
+
+SSL_CTX_add_client_CA() and SSL_add_client_CA() have the following return
+values:
+
+=over 4
+
+=item Z<>0
+
+A failure while manipulating the STACK_OF(X509_NAME) object occurred or
+the X509_NAME could not be extracted from B<cacert>. Check the error stack
+to find out the reason.
+
+=item Z<>1
+
+The operation succeeded.
+
+=back
+
+=head1 EXAMPLES
+
+Scan all certificates in B<CAfile> and list them as acceptable CAs:
+
+ SSL_CTX_set_client_CA_list(ctx, SSL_load_client_CA_file(CAfile));
