bug in meta backend

[Tony Bates <tbates@2keys.ca>]

 Hello all,
 I believe I have stumbled across a bug in the meta backend of 
openldap.    When searching for the same object twice while bound either 
anonymously or with credentials the second search always returns 
"ldap_search: No such object".    This is specific to the meta backend 
as the regular ldap backend doesn't display this problem.

Using 2 command line ldapsearch in sequence is fine: 
bind->search->unbind->bind->search->unbind:

ldapsearch -h localhost -s base -b "ou=ca2,o=test org,c=ca" 
objectclass=* ; ldapsearch -h localhost -s base -b "ou=ca2,o=test 
org,c=ca" objectclass=*

But using ldapsearch with the "-r 2" option returns the proper info for 
the first search but "no such object" for the second search:   
bind->search->search->unbind:

ldapsearch -r 2 -h localhost -s base -b "ou=ca2,o=test org,c=ca" 
objectclass=*

I got the same result using the stock Solaris 2.8 ldapsearch which 
doesn't have the "-r" option but does have a "-f" option which allows 
input from a file for multiple searches.   I built openldap 2.1.12 on 
Solaris 2.8 and I have tried it on a couple of different systems.

I am aware that binding and searching for the exact same thing twice is 
a silly and inefficient thing to do but I have no control over the 
client code that is exhibiting this behavior.   The meta function of 
openldap is a perfect solution to a problem that a vendor won't deal 
with but this little bug prevents it from working completely.

Please advise if I should add this bug to the Issue Tracking System on 
www.openldap.com.
