Subject Re: [users@httpd] mod_authnz_ldap module and Microsoft AD LDAP Server
Date Wed, 22 Oct 2008 15:12:33 GMT
Thank you, André.

That´s because I´m migrating an application from Apache 1.3 to Apache 2.

On Apache 1.3 I was used to Apache::DBI, Apache::AuthDBI, mod_perl,
mod_auth_ldap etc.

Everything worked fine, but ....

Thank you again.
