I have installed openLDAP on a Centos 7 server that is already running FreeIPA for user authentication. http://www.tecmint.com/setup-ldap-server-and-configure-client-authentication
The purpose of openLDAP is for a Nodejs application to manage users for the app. and will be running on separate server.
I can see that slapd is running (ps -ef | grep slapd):
ldap 1287 1 0 06:40 ? 00:00:00 /usr/sbin/slapd -u ldap -h ldapi:/// ldap:///
So I was trying to change the defaults using the ldapadd command and I suspect to be connecting to the FreeIPA LDAP that is configured on the box (on some coammands using -x -h it is asking for a password which hasn't been set yet):
sudo ldapadd -H ldapi:/// -f ldaprootpasswd.ldif
SASL/GSS-SPNEGO authentication started
ldap_sasl_interactive_bind_s: Local error (-2)
additional info: SASL(-1): generic failure: GSSAPI Error: Unspecified GSS failure. Minor code may provide more information (SPNEGO cannot find mechanisms to negotiate)
If I run an ldapsearch then I seem to be able to connect to openLDAP:
sudo ldapsearch -H ldapi:/// -Y EXTERNAL -b "cn=config" "(olcRootDN=*)" olcSuffix olcRootDN olcRootPW -LLL -Q
dn: olcDatabase={2}hdb,cn=config
olcSuffix: dc=my-domain,dc=com
olcRootDN: cn=Manager,dc=my-domain,dc=co
I thought maybe that I could connect externally using a Windows LDAP tool but I get a connection error. I did confirm that the port is open and visible externally.
nmap -p 389 10.18.16.243

Host is up (0.00s latency).
PORT STATE SERVICE
389/tcp filtered ldap

Nmap done: 1 IP address (1 host up) scanned in 19.92 seconds
I tried using -h instead of -H:
sudo ldapadd -a -x -h localhost -p 389 -D cn=Manager,dc=my-domain,dc=com -W -f ldaprootpasswd.ldif
This prompts me for a password but I have only just installed openLDAP and not set a password yet (olcRootPW is in the ldif file I am trying to apply).
Does anyone have experience with openLDAP for user authentication or have any ideas what config needs changing to get this up an running?
