Hi,
I am getting a strange error having upgraded to 2.1.2 from 2.0.18 when trying
to restore my database using slapadd having saved using slapcat.

Testing with adding a single entry using "ldapadd" which used to work fine
gives:
------------- entry to be added -------------------
dn: uid=jc,ou=People,dc=NP,dc=PH,dc=BHAM,dc=AC,dc=UK
uid: jc

-------------- end of entry --------------------------------------

adding new entry "uid=jc,ou=People,dc=NP,dc=PH,dc=BHAM,dc=AC,dc=UK"
ldapadd: update failed: uid=jc,ou=People,dc=NP,dc=PH,dc=BHAM,dc=AC,dc=UK
ldap_add: Object class violation (65)
        additional info: invalid structural object class chain
(inetOrgPerson/account)

which is the same error as the bulk entry problem. It seems to be related to
the "account" object class. Have there been changes to the schema which would
affect this.

cheers
Jim
