*if* you can connect to the LDAP server, then you can also fetch all the 
Data as LDIF. You just have to know the admin  user (and password) to be 
sure you get all the data from the LDAP server.

You'll then just have to inject them in your slave server.

Now, there are more than just the entries, you'll have to deal with the 
server configuration : schemas, index, etc.

If you just want to get back the data, then using a tool like Apache 
Directory Studio, LdapBrower, JExplore, etc could help. They all allows 
you to connect using only LDAP, and get back the data. You can even use 
a command line tool like ldapsearch, which can be installed easily - if 
it's not already present.

Hope it helps, because your story sounds like a nightmare ...
