LDAP is using Apache DS 2.0.0 and Apache Directory Studio 2.0.0 running on Java 1.7.0_51.

Both installed successfully. I have followed the default installation from Getting Started Guide and added sample configuration and sample LDIF.

I'm using the default configuration according to the Getting Started Guide:

Default Port: 10389
Default Bind DN: uid=admin,ou=system
Default Bind Password: secret

When I save the dokuwiki configuration, I got the following error:

User authentication is temporarily unavailable. 
If this situation persists, please inform your Wiki Admin.

What should I do to fix this problem?

Your PHP does not have the LDAP extension installed or enabled. It's needed for AD authentication. Your distribution probably has a separate package for it. Eg. php5-ldap or something.
