Problem while compiling the openldap..............

["Bhavesh kumar Ravjibhai Kamani" <bhavesh@deeproot.co.in>]

   Hello!

         I am a new user to openldap and whn I have started the compiling
the opnldap2.1.29, at that time I have given the option
--enable-ldbm but the error comes like that "ldbm not supported
by the backend". (The error I have written is not exactly in
words ),
but the error is for database.
