Example:
From that web-site I choose the first hyperlink (Auburn University), 
which shows me:
	LDAP-server: donald.duc.auburn.edu
	LDAP-port:   389
	LDAP-base:   o=Auburn University,c=US

I try to get all e-mail addresses (the ldap "mail" attribute) of persons 
who's name start with the letters 'z0':

ldapsearch -x -H "ldap://donald.duc.auburn.edu:389"; \
-b "o=Auburn University,c=US" '(cn=zo*)'

This outputs the following error:
ldap_bind: Protocol error (2)
        additional info: version not supported

So, this server only support the LDAP-protocol Version-2. So I add the 
"-P 2" option to the commandline:

shell$ ldapsearch -x -H "ldap://donald.duc.auburn.edu:389"; \
-b "o=Auburn University,c=US" -P 2 '(cn=zo*)' mail

Then it works.
