Possible bug when searching with an empty filter
------------------------------------------------
Key: DIRSERVER-1275
URL: https://issues.apache.org/jira/browse/DIRSERVER-1275
Project: Directory ApacheDS
Issue Type: Bug
Components: asn1
Affects Versions: 1.5.4
Reporter: Rui Lopes
I'm not sure if this is a bug, but still, I'm going to report it as such.
When I try to do a search using python-ldap:
import ldap
l = ldap.initialize('ldap://localhost:10389')
l.simple_bind_s('uid=admin,ou=system', 'secret')
l.search_s('', ldap.SCOPE_BASE, "", ('vendorName', 'vendorVersion'))
NB: the empty string "" is normally "(objectClass=*)", but for this bug to
happen, pass an empty string, or even "()".
This is was I get in the AD logs:
