Hi All,

I am new to use of ndb with openLDAP. I have established a MySQL Cluster in my network and also compiled the openLDAP with --enable-ndb option. Now when I start the openLDAP with command "slapd -d 5" (To see the debug output), I get the following error:

Configuration error: Error : Could not alloc node id at 192.168.7.40 port 1186: No free node id found for mysqld(API).

My slapd.conf contains :

#######################################################################

database ndb suffix "dc=example,dc=com" rootdn "cn=Manager,dc=example,dc=com" # Cleartext passwords, especially for the rootdn, should # be avoid. See slappasswd(8) and slapd.conf(5) for details. # Use of strong authentication encouraged. rootpw secret

dbconnect 192.168.7.40 ## dbhost - mysql host, where you mysql server resides, used to create schemas dbhost 192.168.7.40 ## dbname - mysql database dbname testing ## dbuser - mysql user name dbuser root ## dbpass - mysql user password (empty in this case) dbpass "" ## dbconnections - how many connections slapd should make to Cluster ## (like ndb-cluster-connection-pool) dbconnections 1 # should only be accessible by the slapd and slap tools. # Mode 700 recommended. directory /usr/local/var/openldap-data # Indices to maintain #index objectClass eq

Output from the ndbd_mgm show command is as follows:

-- NDB Cluster -- Management Client -- ndb_mgm> show Connected to Management Server at: 192.168.7.40:1186 Cluster Configuration --------------------- [ndbd(NDB)] 3 node(s) id=2 @192.168.7.30 (mysql-5.1.44 ndb-7.1.3, Nodegroup: 0, Master) id=3 @192.168.7.56 (mysql-5.1.44 ndb-7.1.3, Nodegroup: 1) id=4 (not connected, accepting connect from 192.168.7.40)

and Config.ini file contains the following data:

Any help on the same is appreciated.
