However, the problem arose when one of our developers miscoded the search filter (badly). A short bit of Jython (utilizing the UnboundID ldap sdk) that can cause the crash is here: from com.unboundid.ldap.sdk import LDAPConnection from com.unboundid.ldap.sdk import SearchScope from com.unboundid.ldap.sdk import SearchResult from com.unboundid.ldap.sdk import LDAPURL attributes = ['objectClass'] ldap_url = "ldap://10.0.228.135:3389" url = LDAPURL(ldap_url) ldap_conn = LDAPConnection(url.getHost(), url.getPort()) #search_result = ldap_conn.search('ou=people,o=lawrence berkeley laboratory,c=us', SearchScope.SUB, '(?uid = \'gahaverkamp\')', attributes) search_result = ldap_conn.search('cn=example', SearchScope.SUB, '(foo =gahaverkamp)', attributes) entries = search_result.getSearchEntries() The actual contents of the filter don't seem to matter too much, so long as filter is bad. The original one sent by the developer resembles the commented line in the script above.

(ITS#7285) Mozilla NSS: default cipher suite always selected
by tim.strobell.ctr＠nrl.navy.mil 04 Jun '12

04 Jun '12

Full_Name: Tim Strobell Version: HEAD OS: RHEL6 URL: ftp://ftp.openldap.org/incoming/tim-strobell-2012060401.patch Submission from: (NULL) (2001:480:20:112:210:18ff:fe19:b000) When using NSS, the default cipher suite selection is used even when TLSCipherSuite is explicitly specified. This behavior was introduced in the patch provided in ITS#6790. At tls_m.c:2221... if ( lt->lt_ciphersuite && tlsm_parse_ciphers( ctx, lt->lt_ciphersuite )) { [ error, return ] } else if ( tlsm_parse_ciphers( ctx, "DEFAULT" ) ) { [ error, return ] } tlsm_parse_ciphers returns 0 on success; the else path is always followed and overrides the previous cipher suite selection.
