SYMPTOMS
When you try to access a multithreaded program that is using the LDAP library WLDAP32.DLL (or dependent technology like ADSI), the program stops responding.



CAUSE
This problem occurs because the LDAP library uses locks to help to protect its connection list, its request list, and its socket list. Different code paths can lead to different lock acquisition order causing a deadlock.
