Topic: Horde does not redirect after login, after upgrade to SME 7.2 (contrib-related?)

[levien]

(Also submitted in Bugzilla as bug #3499, see http://bugs.contribs.org/show_bug.cgi?id=3499))

Yesterday I upgraded our SME server from 7.1.3 to 7.2, using yum and following
the procedure described on the Wiki. After the upgrade, logging into the
webmail / Horde framework stops on the /horde/imp/redirect.php page, without
any further activity or errors in the browser or the httpd-logs. Manually
entering the /horde url or reloading the page does work, and will give you the
Horde site as usual. However, using the /horde/imp or /webmail url just gives
you the e-mail screen, without the sidebar. The problem is browser-independent.

I'm not sure if this is a bug or a contrib-compatibility-problem though.
At the start of the year I installed the horde 3 contrib, together with the
additional kronolith, gollem, mnemo and nag contribs. I tried removing them,
but it didn't make a difference, so I reinstalled them again from smedev (which
I normally keep disabled).

These are the horde-packages I have, from the normal repositories as far as I
know:

horde.noarch                             3.1.4-1.el4.sme        installed
imp-h3.noarch                            4.1.4-1.el4.sme        installed
turba-h3.noarch                          2.1.4-2.el4.sme        installed
ingo-h3.noarch                           1.1.3-2.el4.sme        installed
e-smith-horde.noarch                     1.13.0-21.el4.sme      installed
e-smith-turba.noarch                     1.7.0-16.el4.sme       installed
e-smith-imp.noarch                       1.13.0-10.el4.sme      installed
e-smith-ingo.noarch                      1.1-6.el4.sme          installed

And these I installed from smedev:

 gollem-h3               noarch     1.0.3-1.el4.sme  installed         2.6 M
 kronolith-h3            noarch     2.1.5-1.el4.sme  installed         5.1 M
 mnemo-h3                noarch     2.1.1-1.el4.sme  installed         3.1 M
 smeserver-gollem        noarch     1.0-13.el4.sme   installed          24 k
 smeserver-kronolith     noarch     1.1-10.el4.sme   installed          98 k
 smeserver-mnemo         noarch     1.1-2.el4.sme    installed          23 k
 nag-h3                  noarch     2.1.2-00sme01    installed         3.6 M
 smeserver-nag           noarch     1.1-3            installed          26 k


This is what the logs say when I log in (slightly edited for readbility and
privacy):

[26/Oct/2007:20:50:43 +0200] "GET /horde/imp/login.php HTTP/1.1" 200 2545 "https://server/intranet.html"
[26/Oct/2007:20:50:53 +0200] "POST /horde/imp/redirect.php HTTP/1.1" 200 26 "https://server/horde/imp/login.php"

This is where it gets stuck. I enter the same URL again (by just pressing enter
in the address bar)

[26/Oct/2007:20:51:00 +0200] "GET /horde/imp/redirect.php HTTP/1.1" 302 26 "-"

I now see my webmail, but no sidebar. I remove everything after /horde/ from
the URL, and load the page:

[26/Oct/2007:20:51:09 +0200] "GET /horde/ HTTP/1.1" 200 335 "-"
[26/Oct/2007:20:51:09 +0200] "GET /horde/imp/?frameset_loaded=1 HTTP/1.1" 302 26 "https://server/horde/"
[26/Oct/2007:20:51:09 +0200] "GET /horde/services/portal/sidebar.php HTTP/1.1" 200 3749 "https://server/horde/"
[26/Oct/2007:20:51:10 +0200] "GET /horde/services/javascript.php?file=popup.js&app=imp HTTP/1.1" 200 833 "https://server/horde/services/portal/sidebar.php"
[26/Oct/2007:20:51:10 +0200] "GET /horde/imp/mailbox.php?mailbox=INBOX HTTP/1.1"200 7496 "https://server/horde/"
[26/Oct/2007:20:51:11 +0200] "GET /horde/services/javascript.php?file=tree.js&app=horde HTTP/1.1" 200 3798 "https://server/horde/services/portal/sidebar.php"
[26/Oct/2007:20:51:11 +0200] "GET /horde/services/javascript.php?file=keybindings.js&app=horde HTTP/1.1" 200 1052 "https://server/horde/imp/mailbox.php?mailbox=INBOX"
[26/Oct/2007:20:51:11 +0200] "GET /horde/services/javascript.php?file=popup.js&app=imp HTTP/1.1" 200 833 "https://server/horde/imp/mailbox.php?mailbox=INBOX"

Now it displays like it should.

[26/Oct/2007:20:51:16 +0200] "GET /horde/login.php?logout_reason=logout HTTP/1.1" 302 26 "https://server/horde/imp/mailbox.php?mailbox=INBOX"

Has anyone else had similar problems? Does anyone have a clue as to what have could gone wrong after the upgrade?
(And how to fix it? ).

Do you have any custom-templates defined for Horde?

There is a well-known problem with Horde if you have a customized version of 110AppRegistryHorde in /etc/e-smith/templates-custom/home/httpd/html/horde/config/registry.php/ (see http://wiki.contribs.org/Updating_to_SME_7.2#Webmail_.2F_Horde.)

If you don't have 110AppRegistryHorde do you have any other custom template fragments in /etc/e-smith/templates-custom/home/httpd/html/horde/config/registry.php/?  If so, we may need to update the notes referenced above.

If you do have custom-templates configured you need to copy over the new versions of those templates from /etc/e-smith/templates/home/httpd/html/horde/... and customize the new versions.

I can't find a quick link to what you need to do after fixing the template issue, so try

signal-event post-upgrade ; signal-event reboot

(overkill, but should do the trick...)

I didn't have custom templates for Horde. I did indeed find a reference to the template issue when I did a web-search to see if anyone else had these problems with horde. But thanks for the pointer anyway.

Furthermore, I just discovered the source of my problems. It turned out to be the ionCube PHP accelerator (aka. PHPA) which we installed last year to speed up a slowish web application. Apparently PHPA breaks the redirect-script in the version of Horde that comes with SME 7.2. I removed it and installed eAccelerator instead (using
Sleepy SME's smeserver-eaccelerator RPM), which seems to work just fine.

Thanks!

I don't know anything about PHPA - is it common enough that I should add a note to the 7.2 update instructions?

PHPA is a free but closed-source PHP accelerator, and it is apparently no longer maintained. It is a well-known product, but I do not suspect that many people are still using it. They would probably have run into the same problems I had, and I could not find a single reference to it. Therefore I doubt that it is necessary to add a note to the update instructions (although I might send the Horde people an email telling them to update their documentation regarding php accelerators).

Actually, the only reason why I used PHPA was that we needed to quickly fix some speed issues, and PHPA is the first things that shows up when you google for "PHP accelerator". eAccelerator is the fourth hit though, and at least there's an SME 7.x contrib for that one...
