invalid value for attributeType objectClass

Hello community!

Have a Centos 6.4 server with new openldap 2.4.23-32.el6_4.1 installled. I'm new to ldap and just install it and configure for easy use. I edit only than 2 files olcDatabase={0}config.ldif and olcDatabase={2}bdb.ldif It's starts, I worked with it, add some OU and CN via phpLdapAdmin and tested it on Thunderbird.

But after I decide to restart slapd i got error:

PROXIED attributeDescription "DC" inserted. str2entry: invalid value for attributeType objectClass #0 (syntax 1.3.6.1.4.1.1466.115.121.1.38) slaptest: bad configuration file!

and didn't start.

it's problem with ppolicy and pwdAttribute? How can i solve this?

Thanks for answer!

P.S. Google can't help me or I just don't understand the whole theory.
