Ahhh ok I think this can be fixed easily in LdapStudio or one of the shared
libraries it depends on which probably is responsible for this typo.  Could
you file a JIRA issue for it

This is not good.  Perhaps you can file a JIRA issue about this.  I think
this may be a bug in the schema subsystem but we need to figure it out.
Could you attach the LDIF file to the JIRA as an 'attachment'?  You can file
the JIRA issue for it here:

Yeah this should have worked hence why I think it's a bug in the schema

After doing all of that, everything appears to be fine. I cannot,

I need to narrow down what is causing this: whether it is due to LS or
ApacheDS.  I think it's ApacheDS.  Perhaps the schema has not been enabled
for some reason.  Do me a favor and connect to the server and look at the
cn=moz,ou=schema entry.  Perhaps you can post it's attributes/LDIF here.
But just checking if an m-disabled attribute is present on the entry may
suffice.  If this m-disabled attribute is set to TRUE just modify the entry
so it is set to FALSE or remove the m-disabled attribute altogether.

I think by default newly added schema are disabled.
