Global Catalog: AD objectcategory rewriter

[flo-renaud]

Global Catalog: configure 389-ds AD objectcategory rewriter

In the GC installer, configure the 389-ds AD objectcategory rewriter so that searches with "(objectcategory=foo)" are handled as "(ObjectCategory=cn=foo,cn=schema,cn=configuration,)"

GlobalCatalog: bump 389-ds version for AD filter rewriter for ObjectCategory

With version 1.4.3.6, 389-ds provides a rewriter for filters using objectCategory. The rewriters allows to translate filters such as "(objectCategory=foo)" into "(objectcategory=cn=foo,cn=schema,cn=configuration,$base)"

This feature is needed by the Global Catalog to mimic AD behavior.

With the version bump, the schema is also more strict and fixes are needed for the convert-schema tool:

• the attribute syntax 2.5.5.17 (Sid) that is translated to 1.3.6.1.4.1.1466.115.121.1.40 (octet string) cannot use caseExactMatch and caseExactOrderingMatch for equality and ordering, but should use octetStringMatch and octetStringOrderingMatch instead.
• the objectclass applicationEntity is now defined in 389-ds schema
• the objectclass dMD conflicts with dmd defined in 389-ds schema. Replace with dMD-ad
