#35 Confusing exception handling for NDS servers

[Cato Olsen]

These will cause a
javax.naming.OperationNotSupportedException, with a
NDS error code detailing the actual cause.

Two common causes are "log account expired" and "ds
locked" against one particular LDAP server. See

wec.pdf for descriptions.
