Delete contents of LDAP Database

Hello all, At last I am managing to import everything successfully to OpenLDAP. Hoever, on a regular (possibly daily) basis I need to reimport everything, and make sure that old entries are not lingering. At the moment, to do this I am stopping OpenLDAP, deleting the database files, starting it again, and reimporting everything. I seem to be having problems with some connections lingering when the server is stopped, and it takes a while for these to time out. Is there any way I can delete the contents of the database without needing to know what is in there, using openldap commands, and without stopping and starting OpenLDAP? Thank you,

Chris
