Add timeout for LDAP status calls
I have reproduced this on two seperate TrueNAS systems running 11.1-u5-RC6. While ldap01.tn.ixsystems.com is online, and running in a VM I can join, and disjoin ldap. When I power this VM down TrueNAS is unable to disjoin LDAP.
Software Version: TrueNAS-11.1-U5-RC7 (6ccf719c5)

Other side effects which I may produce two additional tickets for are that I am unable to collect a debug. I have been waiting over 10 minutes. Also I am unable to list the system advanced page in under 30 seconds for the first time when navigating to that page when the ldap server is offline.

- Needs Automation changed from No to Yes
This has been broken since at least FreeNAS 11.0-U4, and all of the 11.1 releases. We do not catch this in automation because our automated tests due not attempt to shutdown the ldap server, or break DNS, and then attempt to disjoin the LDAP server.
#7 Updated by Andrew Walker over 1 year ago
Reproduced problem by configuring LDAP on TrueNAS 11.1-U5.1, then suspending the LDAP server VM. Command
midclt call service.started ldaptimed out. Noted the following code block:
async def _started_ldap(self, **kwargs): if (await self._system('/usr/sbin/service ix-ldap status') != 0): return False,  return await self.middleware.call('notifier.ldap_status'), 
service ix-ldap statusand command hung indefinitely. ix-ldap was hanging because we were performing ldapsearch without a timeout set. I added a timeout based on the sysctl timeout value for determining ldap service status so that the timeout value is ultimately user-configurable.
