If LDAPS is not working, the log file should be checked:
Protocol error: Error reading SEQUENCE response for handle <sockt> : partial
If this entry is shown in the log, the ldap.secure.delay time is set to a value, which is too fast..
To solve this, the delay time can be set to a higher value, with the following command:
visulox config edit -name ldap.secure.delay=<time>
Where <time> is the delay between each request in milliseconds.
If the check command throws the following error:
error: certificate verify failed
The CA file of the issuing authority should be added with -cafile or the parameter -secure should be changed from "verify" to "true".
