Oracle TNS resolving : additional info: objectclass: value #0 invalid per syntax

[HansPeter]

Hello,

I am trying to configure openldap 2.3.39 for TNS resolving in an
Oracle environment.

I was able to create the toplevel domain as follows:
dn: dc=oracle
objectClass: domain
objectClass: top
dc: oracle

Now I want to add the following level like
dn:cn=OracleContext,dc=oracle
cn:OracleContext
objectclass:orclContextAux82
objectclass:orclContext
objectclass:top
orclVersion:90500

But that fails with:
dding new entry "cn=OracleContext,dc=oracle"
ldapadd: Invalid syntax (21)
additional info: objectclass: value #0 invalid per syntax

There are no trailing spaces at the end of every line.

Can someone help?

Regards Hans-Peter
