+.TP
+.B \-r
+Do a recursive delete. If the DN specified isn't a leaf, its
+children, and all their children are deleted down the tree. No
+verification is done, so if you add this switch, ldapdelete will
+happily delete large portions of your tree. Use with care.
+.TP
+.BI \-z \ sizelimit
+Use \fIsizelimit\fP when searching for children DN to delete,
+to circumvent any server-side size limit. Only useful in conjunction
+with \fB\-r\fP.

+.BI \-O \ security-properties
+Specify SASL security properties.

+.BI \-U \ authcid
+Specify the authentication ID for SASL bind. The form of the identity depends on the

+.BI dn: "<distinguished name>"
