Hello,

 

I have just installed openldap Release 2.0.21 and when i try the following

 

/usr/local/bin/ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts

 

i get;

 

ldap_bind: Protocol error
        additional info: version not supported

 

why do i get this?

 

Thanks in advance

 

Regards
