Linux and Unix-Like SuSE
1

I am using apache2-2.0.49-27.8 supply with suse Enterprise 9 CD, the
installation went fine. But am tring to configure apache2 to
authenticate to LDAP, so added "ldap" to /etc/sysconfig/apache2
APACHE_MODULE="ldap"

and the to /etc/apache2/httpd.conf

LDAPSharedCacheSize 200000
LDAPCacheEntries 1024
LDAPCacheTTL 600
LDAPOpCacheEntries 1024
LDAPOpCacheTTL 600

  <Location /ldap-status>

  AuthName "confidential"
  AuthType Basic
  SetHandler ldap-status
  Order deny,allow
  Deny from all
  Allow from 160.70.0.0/16
  AuthLDAPEnabled on
  AuthLDAPURL ldap://160.70.140.152/o=cnn?cn
  AuthLDAPAuthoritative on
  require valid-user
  </Location>

and when I restart my apache I get the following error:

Invalid command 'AuthLDAPEnabled', perhaps mis-spelled or defined by a
module not included in the server configuration

Can you help, please
