Novell eDirectory 8.7.3 for Solaris


Error message in ndsd.log every time the Solaris server is rebooted: "could not open database port 524 already in use".
After reboot eDirectory server (ndsd daemon) can be stopped and restarted without any problems.


The cause of this error message is duplicate startup script links in the /etc/rc2.d directory on the Solaris server. For example, the existence of "S74nds" and "S75NDS" files in the /etc/rc2.d directory will lead to both scripts attempting to start ndsd daemon and the second attempt failing to bind to the port 524.

This is mostly a cosmetic issue, but the deletion of the duplicate link in the /etc/rc2.d directory will fix the problem.
