DIRECTORY: the "cn=schema" subtree is implemented. The Local Unit schema can be retrieved and extended using the 'cn=schema' record.
Foundation: the STSkipList data structure is implemented.
Several internal routines switched to the STSkipList structures to improve performance on large systems (1,000,000+ accounts, 10,000+ domains in queue, etc).

Shared Domains: if LDAP connections to the Central Directory fail, the SMTP module now returns a non-fatal error code for unroutable addresses.
Bug Fix: Directory: Multi-Level searches in Local Units could return incomplete DNs. This could also cause the LDAP module to stop on-the-fly creation of the "mail" attributes.
