+\&\fISSL_CTX_add_client_CA()\fR adds the \s-1CA\s0 name extracted from \fBcacert\fR to the

+\&\fISSL_add_client_CA()\fR adds the \s-1CA\s0 name extracted from \fBcacert\fR to the

+the chosen \fBssl\fR, overriding the setting valid for \fBssl\fR's \s-1SSL_CTX\s0 object.
+.SH "NOTES"
+.IX Header "NOTES"
+When a \s-1TLS/SSL\s0 server requests a client certificate (see
+\&\fB\f(BISSL_CTX_set_verify_options()\fB\fR), it sends a list of CAs, for which
+it will accept certificates, to the client.
+.PP
+This list must explicitly be set using \fISSL_CTX_set_client_CA_list()\fR for
+\&\fBctx\fR and \fISSL_set_client_CA_list()\fR for the specific \fBssl\fR. The list
+specified overrides the previous setting. The CAs listed do not become
+trusted (\fBlist\fR only contains the names, not the complete certificates); use
+SSL_CTX_load_verify_locations(3) 
+to additionally load them for verification.
+.PP
+If the list of acceptable CAs is compiled in a file, the
+SSL_load_client_CA_file(3)
+function can be used to help importing the necessary data.
+.PP
+\&\fISSL_CTX_add_client_CA()\fR and \fISSL_add_client_CA()\fR can be used to add additional
+items the list of client CAs. If no list was specified before using
+\&\fISSL_CTX_set_client_CA_list()\fR or \fISSL_set_client_CA_list()\fR, a new client
+\&\s-1CA\s0 list for \fBctx\fR or \fBssl\fR (as appropriate) is opened.
+.PP
+These functions are only useful for \s-1TLS/SSL\s0 servers.
+.SH "RETURN VALUES"
+.IX Header "RETURN VALUES"
+\&\fISSL_CTX_set_client_CA_list()\fR and \fISSL_set_client_CA_list()\fR do not return
+diagnostic information.
+.PP
+\&\fISSL_CTX_add_client_CA()\fR and \fISSL_add_client_CA()\fR have the following return
+values:
+.Ip "1" 4
+.IX Item "1"
+The operation succeeded.
+.Ip "0" 4
+A failure while manipulating the STACK_OF(X509_NAME) object occurred or
+the X509_NAME could not be extracted from \fBcacert\fR. Check the error stack
+to find out the reason.
