I am starting OpenLDAP with -f slapd.conf -F /path/configdir to convert my
configuration to LDIF, including customized schema.
My customized schema is split in several files. Sometimes, the attributes
defined in one of these files are not generated in the configdb LDIF files (the 
cn={n}xx.ldif file in the /path/configdb/cn=config/cn=schema directory does not
contain any olcAttributeTypes values, though it contains the corresponding
olcObjectClasses attributes).
After several tests, the problem seems to come from an attribute with
Certificate syntax: as soon as one xx.schema file contains such an attribute,
the corresponding {n}xx.ldif file does not contain any olcAttributeTypes
attribute).
This works with core.schema (usercertificate for example), but I can't see any
difference with my certificate attribute.
