Typically that error means there is a cn=config already when you try to slapadd it.

Does anyone know the source and resolution to this installation error? Interestingly, if I use an alternate command I'm able to bring up the server, in which I can see via debug it's responding to the client.

I'm following: https://www.openldap.org/doc/admin24/quickstart.html

Import the configuration database su root -c /usr/local/sbin/slapadd -n 0 -F /usr/local/etc/slapd.d -l /usr/local/etc/openldap/slapd.ldif

and encounter this error. I see many posts on it with no resolution. I'm using MacPorts openldap 2.6.10.

Interestingly, if I invoke this suggested command: /opt/local/libexec/slapd -f /opt/local/etc/openldap/slapd.conf -F /opt/local/etc/slapd.d

I can invoke slapd and my LDAP server comes up. It responds back to: /opt/local/bin/ldapsearch -x -b '' -s base '(objectclass=*)' namingContexts

but without dc=site,dc=com only blank dn:

dn:

# search result search: 2 result: 0 Success

# numResponses: 2 # numEntries: 1

There is nothing in my etc/slapd.d directory.

I try: ldapadd -d 3 -x -D "cn=Manager,dc=p0,dc=mac" -W -f file.txt Enter LDAP Password: ldap_bind: Invalid DN syntax (34) additional info: invalid DN

Not sure how to approach this and any guidance appreciated.
