Invalid Structural Object Class Chain (account/person)

[Paul Thomas <pwthoma@anc.net>]

I'm attempting to populate our LDAP database and I plan on using it for 
both authorization and as a corporate address book.  When I attempt to 
import the LDIF file I get the following.

ldapadd -a -W -x -D "cn=Manager,dc=anc.net,dc=anci" -f pwthoma.ldif
Enter LDAP Password:
adding new entry "uid=A0971217/-2663,ou=People,dc=anc.net,dc=anci"
ldapadd: update failed: uid=A0971217/-2663,ou=People,dc=anc.net,dc=anci
ldap_add: Object class violation (65)
additional info: invalid structural object class chain (account/person)

Now, I understand that the problem is that I've got the following in my 
LDIF file but what I don't know is what the preferred method of addressing 
this is.  I don't think modifying the account or person objectclass in 
their schema is ideal in this case as I'm sure they are defined that way 
for a reason.  I would, however, prefer to keep all this in the same ou 
(ou=People,dc=anc.net,dc=anci)

Here is my LDIF file if it's helpful
