You can make a call to the ldap_ber_free() function to free BerElement structures allocated by ldap_first_attribute() and by ldap_next_attribute() function calls. When freeing structures allocated by these functions, specify 0 for the freebuf argument. The ldap_first_attribute() and by ldap_next_attribute() functions do not allocate the extra buffer in the BerElement structure.

For example, to retrieve attributes from a search result entry, you need to call the ldap_first_attribute() function. A call to this function allocates a BerElement structure, which is used to help track the current attribute. When you are done working with the attributes, this structure should be freed from memory, if it still exists.

This function is deprecated . Use the ber_free() function instead.
