repeated search entry

[Yanlin Peng <kamela@mail.ustc.edu.cn>]

when I use LDAP-API 'ldap_search_s'offered with openldap to search
entry, I get duplicate entries. Do you ever meet this?
I write as follows.

ldap_search_s(ld,baseDn,LDAP_SCOPE_SUBTREE,"objectclass=*",allAttrs,0,&res);
m=ldap_first_message(ld,res);
while(m!=NULL&&ldap_msgtype(m)==LDAP_RES_SEARCH_ENTRY)
{
	for(e=ldap_first_entry(ld,m);e!=NULL;e=ldap_next_entry(ld,e))
	{...}
	...
	m=ldap_next_message(ld,m);
}
