Hello All,

coming back to Mercury I did a test install with Mercury 4.91 and Roundcube 1.5. Can't use Roundcube 1.6 as the webserver is still running php5.6.40. After install I ran into the following problem:

According to Mercury session log and roundcube imap log I get a * LIST (\Noselect) "/" "" error. User is directly successfully loged out.

Both logs are the same as shown below

Assuming that I am missing, or have wrong settings in some config settings in Roundcube.
Looking through the forum posts, my particular problem did not come up.
Maybe someone could point me in the right direction.

BTW, Squirrelmail is working fine, but wanted to offer my users something different.

Johannes

I don't know how or if I can help you, but I had Roundcube 1.5 running with Mercury 4.90 before without any problems. Currently using Roundcube 1.6 and Mercury 4.91, and no problems. In the past I also ran SquirrelMail, but once Roundcube was working I removed it.

I'm not sure that the line with Noselect is an error. I looked at a session log on Mercury and I have one line with Noselect that says:
09:52:02.426: << * LIST (\Noselect) "/" "Recent search results"<cr><lf>

Is it possible that your Noselect line is finding a folder without a name?

Does this happen for all users, or just one or some?

One other observation, you mention a test install with 4.91, but your log shows 4.90. Probably not significant...

Tony

After I replied, I enabled IMAP debugging on Roundcube, and the log shows that RC logs out after loading folders.

After logging in to Roundcube, look in Settings, Special Folders to match IMAP folders to RC folders?

Tony

Hi Tony,

thank you for your reply.
Yes, the testing system is Mercury 4.9.0, mentioned that wrong in my post.
This is a test setup as I have to install a new system from scratch.

The user has the initial folders which were created by Pegasus mail. I can acces them in Pegasus and in Squirrelmail.

The login / Logout happens so fast, that I only get a "Session logout" message right after login. There is no chance even to go into RC to look at the Settings.

I will post later today, as I am not right now at the test machine, the config file of RC, as I assume that I have there some wrong or missing settings in regards to the Folder delimiter.

Maybe that will give some clues ?

I really think the problem is not in the log you have posted here. When I login with Roundcube, the log starts out almost exactly like the log you posted:

But, the difference is after the logout completes, it immediately connects again and performs another action.

I vaguely remember initially having a problem with the database connection or a permission problem. It was too long ago to recall the details, and the logs don't go back that far.

Have you checked the other Roundcube logs? Might be a hint in one of them.

Tony

Tony,

I checked Mysql, the user is added and I noticed as well a connection in Mercury-I live screen a connection from Mysql. RC imap log and Mercury imap session log show the same results.

I am just wondering about the failed session authentication. And that must be the connection from Mysql as it shows in Mercury-I ive window a 0 sec. connection.
Not sure why/what this is, as other php application with sessions don't show any problems.

So, further digging is required.

Just to make sure, below is my RC config. Maybe you can compare and spot some incorrect settings ?

I see you have set:

$config['imap_dual_use_folders'] = true;

I did not set that because I'm pretty sure Mercury doesn't support folders containing folders and messages. I left it at null. But I don't think that is the cause of your login problem.

I suggest you also look at your Apache error logs to see if there's anything helpful there.

Tony

Hi Tony,

Problem is solved. I got it working.

My webserver log didn't show any errors or notices and no php errors either.
After installing Apache, it worked right "out of the box". It seems that RC is very much geared toward Apache and/or NGinx. No changes in regards to the database MySql and to the config file. I just changed the "imap_dual_use_folders" setting to "false.

Thank you for your time and effort looking into my problem.
