Race condition in DNParser
--------------------------
Key: DIRLDAP-70
URL: http://issues.apache.org/jira/browse/DIRLDAP-70
Project: Directory LDAP
Type: Bug
Reporter: Emmanuel Lecharny
Priority: Blocker
I got an exception while parsing a DN under heavy load. It seems that
theDNParser is not thread-safe
Here are the traces (some logs have been added) :
2354> --AuthenticationService -- [ERROR] Authentication failed :
null
4912> --SimpleAuthenticator -- [ERROR] Error : first argument was
not a distinguished name : ou=groups,ou=system/Parser failure on name:
ou=groups,ou=system
Antlr exception trace:
line 1:1: unexpected token: ou
