Update from 4.1-5 / modified Apache configuration files

Hi,
we can’t update from 4.1-5 errata484:

/etc/univention/templates/files/etc/apache2/sites-available/univention-directory-manager
WARNING: There are modified Apache configuration files in /etc/univention/templates/files/etc/apache2/sites-available/.
Please restore the original configuration files before upgrading and apply the manual changes again after the upgrade succeeded.
This check can be skipped by setting the UCR
variable update42/ignore_apache_template_checks to yes.
Error: Update aborted by pre-update script of release 4.2-0
exitcode of univention-updater: 1
ERROR: update failed. Please check /var/log/univention/updater.log

We never touched /etc/univention/templates/files/etc/apache2/sites-available/univention-directory-manager manually, there is no .dpkg-dist of this file anywhere.
We replaced the local file with the original one from a completely fresh installation of 4.1-5, but update still won’t contibue.

Any ideas?

thanks
Sascha

noone?

thanks again

What’s the output of

dpkg -l | grep '^rc'
univention-check-templates

#4

The programs checks for dpkg-{new,dist} files and if the md5sum of the file differs from the one at package installation time. If you are sure there are no changes you might lose, try deleting the file and reinstall the package it came from:

dpkg -S /etc/univention/templates/files/etc/apache2/sites-available/univention-directory-manager
univention-management-console-module-udm: /etc/univention/templates/files/etc/apache2/sites-available/univention-directory-manager

rm /etc/univention/templates/files/etc/apache2/sites-available/univention-directory-manager
univention-install --reinstall univention-management-console-module-udm

As @SirTux wrote, you can then check the output of univention-check-templates

hi, thanks everyone.

whoops…this seems quite a lot to me:

I think this will solve your problem:

aptitude purge univention-webui-style

By the way, so on this system was Samba installed but actually is not?


#7

Hi,

yes seems quite so.
Samba might have been installed a while ago, but is defo not needed at all. UCS is really just an IMS for OX in this case.
any idea how to clean this thing out and best proceed for the update?

thanks
Sascha


#8

Ok then I think you can delete all this packages:


#9

All these you’re saying:
dpkg -l | grep ‘^rc’

Thanks
Sascha


#10

ok… that seemed to have done the job. purged all the rc packages and upgraded to 4.2-3 without problems.
But now Open-Xchange will not let anyone login anymore:

https://pastebin.com/zhjj03ce

Seems like apache has some problem, any idea?

[Sun Dec 10 18:02:16.786248 2017] [proxy:error] [pid 6035] AH00959: ap_proxy_connect_backend disabling worker for (localhost) for 60s

so near to solving this…appreciate any hint!

thank you
Sascha


#11

Was it working before the upgrade?


#12

sure…worked perfectly


#13

noone has any idea here?


#14

ok, I now know, what the problem is:
The TLS connection to LDAP is not being established, maybe because an old SHA1 or MD5 signed cert is being used.
We do in fact use a commodo DV cert for apache, cyrus and postfix, which does support TLS v1.0 - v1.2 however.
But is this the certificate we’re talking about for the LDAP connection? I don’t think so really.
So the question would be: How do we get the LDAP connection working, would we need to rebuild the certificate, or not?

Thanks
Sascha


#15

Hey,

how do you figure that the connection to the LDAP server is what’s not working? Do you have any log messages that say so?

Normally the Univention LDAP servers (both the OpenLDAP one and Samba’s) use a certificate generated by the local UCS CA. Both are independent of other services that might use official, external certificates such as web or mail servers. I’ve never seen the certificate for the LDAP servers changed to a non-UCS-CA one, and I cannot think of a good reason for such an action.

Therefore the certificate should be OK.

One possibility is that the configuration data for Open-Xchange’s authentication plugin isn’t in sync. That file is /opt/open-xchange/etc/authplugin.properties. The most important thing you can check is whether the value given in com.openexchange.authentication.ucs.bindPassword is the same as the value in the file /etc/machine.secret as the machine’s LDAP account is usually used for binding to the LDAP server. It’s possible the machine account’s been changed in the meantime, but the password hasn’t been updated in the authplugin.properties file.

A somewhat better test would be to try to run an LDAP search with the values given in the file. Run the following command (copy & paste is highly recommended) which reads all relevant connection parameters from that authplugin.properties:

ldapsearch \
  -H $( awk -F= '/^com.*ldapUrl/ { print $2 }' $file ) \
  -b $( awk -FbaseDn= '/^com.*baseDn/ { print $2 }' $file ) \
  -D $( awk -FbindDn= '/^com.*bindDn/ { print $2 }' $file ) \
  -w $( awk -F= '/^com.*bindPassword/ { print $2 }' $file ) \
  -s base -x dn

It should output the top-most LDAP object’s DN.

Kind regards
mosu


#16

Hi Moritz,

this sounds extremely feasible to me. will try and test!
Thanks
Sascha


#17

I just noticed that I left out a rather important line before that ldapsearch:

file=/opt/open-xchange/etc/authplugin.properties

Sorry about that :slight_smile:
