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.
