Only one default BASE is used in ldap.conf.

Your slapd.conf syntax is bogus, but what you want is readily supported in
OpenLDAP 2.1. Each naming context must live in a valid database, and the
order in the slapd.conf file is significant - you must define the deepest
subtrees before you define their parent subtrees. For this example, you could
use:

 database bdb
 suffix	"dc=student,dc=gpc,dc=edu'
 rootdn	"cn=Manager,dc=student,dc=gpc,dc=edu"
 subordinate

 database bdb
 suffix	"dc=employee,dc=gpc,dc=edu"
 rootdn	"cn=Manager,dc=employee,dc=gpc,dc=edu"
 subordinate

 database bdb
 suffix	"dc=gpc,dc=edu"
 rootdn	"cn=Manager,dc=gpc,dc=edu"

See the slapd.conf manpage for information on the "subordinate" keyword,
which causes all the magic to happen.

Note that each database must actually contain an entry corresponding to its
suffix. E.g., you must create a valid entry for dc=gpc,dc=edu in the
dc=gpc,dc=edu database.
