It sounds like you have several misconceptions about LDAP. LDAP doesn't
use tables, it's not a relational database. Instead it uses entries which
are collection of attributes and values. You can think of an entry
as a record in a database. Attributes are like fields. There's a special
attribute called "objectclass" which defines what attributes are required
and which ones are allowed for an individual entry in the server's schema.

I would really recommend that you spend some time reading up on LDAP
before you try to go much farther. LDAP is not that difficult, but like
any technology you must spend some time learning it first. I'd recommend
my book (of course :), "Implementing LDAP" as well as Howes,
"Understanding and Deploying LDAP Directory Services" and a new one,
"Implementing Directory Services" from Archie Reed (haven't read this one
yet, so I can't really vouch for it). 

So the question of "can you create a new table", can mean one of 2 things
in an LDAP context. Can you add a new entry? Yes. Assuming that the
account your authenticated to the server as has rights to do so & that the
new entry matches a valid objectclass schema. The other context is "can I
extend the server's schema"? The answer is generally yes, but the
particulars will depend upon what type of LDAP server you're using. If
your're using openLDAP, you'll have to change the schema with a text
editor because it is currently only an LDAP v2 server. If you're using an
LDAP v3 server, you can dynamically extend the server's schema.

As for changing the base of your LDAP server, without knowing what LDAP
server you're running (I'm guess Netscape's because of the default base),
it's easiest to just uninstall the software and then reinstall. There are
ways to change it 'on the fly', but considering your current lack of LDAP
knowledge, I won't go into more detail.
