The LDAP schema isn't viewable in the regular view of the LDAP
tree. It's stored in a parallel universe called cn=config, the brain
child of something called LDAP OLC (on line configuration). Someone
thought it was a good idea to allow runtime configuration of
LDAP. They forgot the part of being easy and maintainable on par with
other Unix services on the server. Hence, they abandoned configuration
files under /etc to go with this parallel LDAP tree under
cn=config. Oh well, in any case, to view it, you can use slapcat:
$ slapcat -H "ldap:///cn=config??sub?(olcDatabase=*)"
