US Patent:

7373348, May 13, 2008

Filed:

Apr 14, 2005

Appl. No.:

11/106396

Inventors:

Jason Murray Bell - Austin TX, US
Mark Joseph Cavage - Cedar Park TX, US
Kristin Marie Hazlewood - Austin TX, US
Richard Allyn Heller - Austin TX, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

G06F 17/30

US Classification:

707 10, 707102

Abstract:

Each LDIF entry of a directory tree is read, split to a domain of LDIF fragments (corresponding to backend servers) and written to each LDIF fragment. The split may be accomplished through a hash function, establishing, for that iteration of LDIF entry, a write file. The LDIF entry is appended to the write file. A subsequent LDIF entry is read. A corresponding LDIF fragment is determined, which need not be different from the LDIF fragment to which the first LDIF entry was written. The current LDIF entry is written to the currently selected write file. The process continues until all LDIF entries are exhausted from the directory tree. LDIF fragments are each copied to distinct backend servers, where, each LDIF fragment may be loaded into a distributed directory data structure.

International Classification:

G06F 17/30

US Classification:

707769

Abstract:

A directory server handles requests for values of dynamic attributes by providing at least one declaration for an attribute to be handled as a real-time attribute associated with but external to a directory structure; receiving a directory access protocol request for access to an attribute value from the associated directory structure; detecting requested access to an attribute declared as a real-time external attribute; resolving a real-time value by obtaining an attribute value from a real-time source external to the directory structure; converting the obtained attribute value from a real-time attribute to a static attribute, wherein the real-time attribute is incompatible with the directory access protocol, and wherein the static attribute is compatible with the directory access protocol; and returning to a requester the converted real-time attribute directly in the directory access protocol, wherein storing and updating of the converted real-time attribute value in the directory structure is eliminated or avoided.

International Classification:

G06F 17/30

US Classification:

707769

Abstract:

Real-time attributes are processed according to a syntax schema for a directory access protocol service by associating by a computer a real-time attribute with a directory structure, the real-time attribute being externally stored from the directory structure; responsive to an access request via a directory access protocol for access to a database value for the real-time attribute, obtaining by a computer a current value from a real-time data source external to the directory structure, and converting by a computer the obtained value from a format not compatible with the directory access protocol to a compatible format; and returning by a computer to a requester the converted real-time attribute directly in the directory access protocol, wherein storing and updating of the converted real-time attribute value in the directory structure are eliminated or avoided.
