Hi,

 you sure that issue still exist in latest Pro?

In revision 8295 (0.16.12.8295) fixed sessions race condition which can cause such behavior.

Other situations that can cause such behavior:

 - your client IP dynamic: for resolve this goto page "Global settings -> Edit -> Authentication" and switch option "Session bind to IP" to False.

 - your browser Updated to an new version.

I also get this using local authentication (ie. Accounts created directly through Observium) as-well – using PHP7 and CentOS7.

 

But it’s inconsistent – sometimes I can go days without seeing the issue and then it will just happen a few times (eg. sometimes once every few hours, sometimes multiple times within an hour). Bit hard to predict when it’ll happen to capture useful logs though.

 

It’s probably also worth noting that we still had this problem when our Observium was running off Debian and PHP5 (specific versions, I can’t remember them). The database was migrated to the CentOS7 box mentioned above so one could say that’s the common factor here, if that’s relevant.

 

There is also another thing, which I believe is unrelated but I’ll mention it just in-case. I have noticed if you leave Observium at its login screen for a very long period of time (overnight), and attempt to login, it will just boot you back to the login page. I’m assuming this is just because the PHP session has expired though.

Hi Dan,

We've had reports of this, and have tried quite a few things to fix it... unfortunately I don't have a lot of news about this, as we're kind of out of ideas of what is happening. Useful datapoint that you included you use LDAP auth.

Does anyone else have issues with random logouts on 17.1.8318?  I will be working on or looking at something, clicking menu's, and then all of the sudden i'm at the login screen.  Sometimes it happens after a few minutes of the initial login, and sometimes its hours later.

 

PHP 5.6.30

Centos 7.3.1611

Active directory authentication.

 

Dan.
