Distributed directory deployment
First Claim
1. A method for creating at least two LDIF (Lightweight Directory Access Protocol Data Interchange Format) fragments the method comprising the computer implemented steps of:
- reading a setup configuration having a first LDIF fragment name corresponding to a first LDIF fragment and a second LDIF fragment name corresponding to a second LDIF fragment;
reading a plurality of successive LDIF entries from the directory information tree (DIT);
determining for each LDIF entry whether each LDIF entry should be written to a first LDIF fragment or to a second LDIF fragment based on a split function; and
writing each LDIF entry to the first LDIF fragment or to the second LDIF fragment based on the split function.

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.

8. A setup computer for creating at least two LDIF (Lightweight Directory Access Protocol Data Interchange Format) fragments comprising:
-
a first processor means for reading a setup configuration having a first LDIF fragment name corresponding to a first LDIF fragment and a second LDIF fragment name corresponding to a second LDIF fragment;
a second processor means for reading a plurality of successive LDIF entries from the directory information tree (DIT);
a first hard disk drive for determining for each LDIF entry whether each LDIF entry should be written to a first LDIF fragment or to a a second LDIF fragment based on a split function; and
a second hard disk drive for writing each LDIF entry to the first LDIF fragment or to the second LDIF fragment based on the split function. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A computer program product in a computer readable medium for creating at least two LDIF (Lightweight Directory Access Protocol Data Interchange Format) fragments the method comprising the computer implemented steps of:
-
first instructions for reading a setup configuration having a first LDIF fragment name corresponding to a first LDIF fragment and a second LDIF fragment name corresponding to a second LDIF fragment;
second instructions for reading a plurality of successive LDIF entries from the directory information tree (DIT);
third instructions for determining for each LDIF entry whether each LDIF entry should be written to a first LDIF fragment or to a second LDIF fragment based on a split function; and
fourth instructions for writing each LDIF entry to the first LDIF fragment or to the second LDIF fragment based on the split function. - View Dependent Claims (16, 17, 18, 19, 20)
