First, I may ask the question in a different way: can we have two defined Directory tag for one directory?
- users with source 192.168.1
<Directory /var/www/html/directory>
Order Deny,Allow
Deny from all
Allow from 192.168.1
</Directory>
- other users (need to be authenticated using LDAP):
<Directory /var/www/html/directory>
AuthName "LDAP Authentication"
AuthType Basic
AuthBasicProvider ldap
AuthzLDAPauthoritative off
AuthLDAPURL ldap://192.168.1.3/dc=example,dc=com?uid?sub?(objectClass=*)
Require valid-user
</Directory>
