If a directory is stored directly in a dataabse the directory information would have to be mapped to multiple databases. Also the directory service provides attributes, which facilitiate update and search of directory information. The alternative is using the WHERE cluases in SQL statements to update and search.
Please also refer "LDAP vs relational database", which is for OpenDS, but most of the advantages also apply to OpenLDAP. Both OpenDS and OpenLDAP directory servers are based on the embedded Berkeley DB database.

Also DBAs would be required to administer the database.
