[CAUSE]The tmnxLdapServerOperStateChange notification is generated when the tmnxLdapServerOperState has transitioned either from 'outOfService' to 'inService' or from 'inService' to 'outOfService' state. [EFFECT]If tmnxLdapServerOperState has transitioned to 'outOfService' state then the particular LDAP server connection is not available for use. If tmnxLdapServerOperState has transitioned to 'inService' state then the particular LDAP server connection is available for use. [RECOVERY]If the new state corresponds to the tmnxLdapServerAdminState, then this is the desirable behavior and no recovery is needed. If the new state of the tmnxLdapServerOperState object is 'outOfService' while the value of the object tmnxLdapServerAdminState is 'inService', make sure that the LDAP server connection parameters are properly configured and the LDAP server is reachable.
