Subject [jira] [Created] (DIRAPI-288) Space between LDAP filter conditions causes NPE
Date Wed, 21 Dec 2016 21:32:58 GMT
Carlo Accorsi created DIRAPI-288:
------------------------------------

             Summary: Space between LDAP filter conditions causes NPE
                 Key: DIRAPI-288
                 URL: https://issues.apache.org/jira/browse/DIRAPI-288
             Project: Directory Client API
          Issue Type: Bug
    Affects Versions: 1.0.0-RC2, 1.0.0-M32
         Environment: Win7 x64 Java 1.7.0_51 - Query against Active Directory 2008
            Reporter: Carlo Accorsi
            Priority: Minor


Hi, When setting a filter on a request having multiple conditions, if there are spaces after
operators or between clauses, this causes a NullPointerException. I'm not sure but I think
the spec ignores this type of white space. I tested the same problematic query with JNDI and
it executes without issue. I don't think the backend LDAP vendor matters, it seems to fail
in the api before the request is sent. 

Query with no spaces between parenthetical conditions or after logical OR '|' and the query
executes as expected.

(|(memberOf=cn=group1,ou=test)(memberOf=cn=group2,ou=test))

Having a space after the logical OR operator and/or between conditions (not sure which) throws
NPE.

Structure a query like this to reproduce where ^=space
(|^(memberOf=cn=group1,ou=test)^(memberOf=cn=group2,ou=test))



Found in api ver M32 and tested also in RC2..
