[ZendTo] LDAP authentication

[Scott Silva]

I never got it working on my system... If I can't get it working I will probably have to drop the software when Windows forces the change...

Subject: Re: [ZendTo] LDAP authentication

Jules,
Is there anything special required to get LDAP working with SSL?  I tried setting 'authLDAPUseSSL' to true, rebooted and logins fail.  I then tried adding the port number (after a colon) to the address in 'authLDAPServers' and rebooted and logins still fail.  If I use an ldap browser to connect, it works although it does complain about the certificate.  Do I need to import the certificate for ZendTo to be able to connect?  If so, do you have any directions for this?

Thanks!
Ken

I always forget about it too!

And I wrote it :-(

Ken,

ZendTo actively locks out (for 24 hours) users who have failed too many login attempts in a day.
This protects against hackers using your ZendTo to attempt to find passwords by brute force.
There are 2 ways of seeing who is currently locked out, and to manually unlock them immediately:
1. The web interface for an Admin user (it's one of the red buttons).
2. But if you can't get to that, then run /opt/zendto/bin/unlockuser and it will show its command-line usage. You should just be able to run
sudo /opt/zendto/bin/unlockuser -a

to unlock every temporarily-locked account.
Hope that helps,
Jules.

And now it is working again. Since a trace on my ldap server showed I wasn't even getting a query from ZendTo, I decided to see what my firewall was seeing. ZendTo is installed in my DMZ. I log into the firewall and do a couple of logins to ZendTo with other accounts and watch what shows up in the firewall. Then I try my login again and it works and shows up in the firewall as expected. I had changed nothing, I just logged into the firewall to see the activity. Frustrating not knowing why, but things are working again. I assume the firewall between the DMZ and the rest of the network was the issue, but I have no idea how or why since it just started working.

My apologies for all the clutter on the mailing list.

I have other software that also does LDAP authentication and my account works fine there. A trace on my LDAP server shows the login happening as expected. So it is as if ZendTo thinks my account is not an LDAP account and is trying to authenticate elsewhere and failing.

Doing some more digging into this and not making much progress. I was working on moving ZendTo ldap authentication from port 389 to port 636 (SSL). Something wasn't working right, but now my account is locked out of ZendTo. Doing a trace from my LDAP server shows that I don't even get a request from ZendTo. ZendTo is working for all accounts except mine. Is there anything at all within ZendTo that might give me a clue as to what is going on?
