A network service error has occured on failed login.

[nadsab]

Hi there,

Have a problem and hoping to get some advice. My sever SSL cert expired and I am about to install a new one. As a temporary measure I clicked to add an exception to the expired cert in firefox browser and can log into ZImbra admin OK. The problem is, even though I am able to log in via admin, I can't log in to my user account. I also tried changing passwords a few times on the user account and that did not work either.

The error message I am getting on the failed login for the user account is:

“A network service error has occured (zclient/io)”.

I am thinking this may be related to the expired server SSL cert or the browser exception I added, however how can it be that I can log into admin and not a user account?

Is there any way I can get access to the user account? Because the user account in question is my main contact account for my domain registrations and unless I can get in to that I can't confirm my new SSL certs unless I change my contact info at my registrar and that usually takes a few days to update

I had no problems with logins previously...

Thanks much for any advice.

Can you connect via HTTP ? or use the IP address instead for your ZCS server.

Hi thanks uxbod,

I can access the login page for ZCS admin via IP - by using the server IP address. For example when I use the server ip address (which is the IP also designated for zimbra admin logins) and port 7071, for example, instead of using https://serverdomain.net:7071:

for admin:

https://123.456.789.012:7071 and then I can bring up the admin login page and log in that way AOK as admin.

However, I can't do the same for users. My login URL for users is https://webmail.serverdomain.net and when I substitute serverdomain.net with the server ip I can't access just a user's login page.

For example when I substitute the IP in the above as thus: https://webmail.123.456.789.012 I get an address not found error.

I never have been able to login via http non secure...

Just so you can get into your admin account try using View Mail from the Admin GUI

I tried that via admin GUI and got a 404 not found error.

Hi again,

Would anyone have any ideas or advice as to how I could trouble shoot this? Right now my server is effectively dead in the water because I can no longer access any email accounts due to this problem..

I have root access to the server, wondering where to start to solve the problem...

Any advice greatly appreciated.

Why not Recreating a Self-Signed SSL Certificate - Zimbra :: Wiki and once logged in get your information and the switch back to a commercial certificate ?

[nadsab]

OK thanks I will give that a try and post back later the results.

Forgot to include in the original post I am running version 5.0.2.

[nadsab]

OK I think I successfully generated a new self signed certificate via the admin GUI.

How would I restart ZCS server to apply the changes? For ZCS 5.0.2 running on Centos?

And can I restart ZCS if logged in as root via CLI? Or would I have to be logged in under a zimbra user name?

And do I also need to restart apache? Or is an apache restart only required for ZCS 4.5?

su - zimbra
zmcontrol stop ; zmcontrol start

Oh and if you are running 5.02 you should really look at upgrade Zimbra!
