What returns LDAP_BUSY?

["David Nelson" <dnelson@apexvoice.com>]

I'm writing an LDAP Client using the 1.2.x library which basically does
binds, searches, adds, deletes, modifies and unbinds.  I'm 
trying to handle
as many of the error codes as possible.  Can I expect to ever get an
LDAP_BUSY returned for a bind operation?

Thanks in advance,
