[jira] Resolved: (DIRSERVER-1275) Possible bug when searching with
an empty filter
[ https://issues.apache.org/jira/browse/DIRSERVER-1275?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Emmanuel Lecharny resolved DIRSERVER-1275.
------------------------------------------
Resolution: Invalid
This is a problem with Python Ldap implementation which does not generate a correct PDU. The server correctly reject the request because there is no filter in it, when it's a mandatory field.

> 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 "()".
