SSL and HTTPD

[everestrus]

Hi there

I have some problem with SSL in HTTPD,
When I am starting httpd it is showing me follow error
Starting httpd: Syntax error on line 51 of /usr/local/directadmin/data/users/gbavatar/httpd.conf:
Invalid command 'SSLEngine', perhaps mis-spelled or defined by a module not included in the server configuration

my question is how to set up that DA add follow record
SSLEngine on
SSLCertificateFile /etc/httpd/conf/ssl.crt/server.crt
SSLCertificateKeyFile /etc/httpd/conf/ssl.key/server.key

in directive <ifDefine SSL></ifDefine>

and how to set up that DA add httpd.conf record for account to main httpd not to /usr/local/directadmin/data/users/

Thanks
