Troubleshooting the sensor

This topic describes common problems that occur with the LDAP sensor and presents solutions for those problems.

Error occurs during a discovery

Problem

The sensor discovery finishes with the following error message:

CTJTD0421E The LDAP server contains the following unexpected attributes: 
javax.naming.AuthenticationNotSupportedException: [LDAP: error code 13 - confidentiality required]

Solution

The LADP server requires encryption. The LADP sensor cannot carry out a discovery if the LADP server requires encryption, disable the encryption on the LADP server.

Sensor cannot display all attribute information

Problem: The following attribute information is not displayed after running a discovery: LDAP Version, Threads, and Total Connections.
Solution: Enable the LDAP application monitor to discover LDAP Version, Threads, and Total Connections.

Duplicates of LDAPService instances

Problem: When the LDAP server listening port changes between two discoveries, duplicates of LDAPService instances might occur after each discovery.
Solution: Add target server's session credentials to the access list. Check whether the ComputerSystem sensors, such as LinuxComputerSystemSensor, are enabled in the discovery profile. After LDAPServiceAgent run, LDAPService instances are merged, if discovered on the same host.
