In short: config syntax for LDAP authorization changed a LOT, and is
not well described anywhere. While updating from apache 2.0, the user
should be warned about necessary configuration changes.
A bit longer: I use LDAP-authorization for my apache2 installation.
Today I tried upgrading my apache from 2.0 to 2.2. And ...
1) First surprise happened while updating
Preparing to replace apache2-mpm-prefork 2.0.55-4.1 (using .../apache2-mpm-prefork_2.2.3-3_i386.deb) ...
Stopping apache 2.0 web server...Syntax error on line 1 of /etc/apache2/mods-enabled/auth_ldap.load:
Cannot load /usr/lib/apache2/modules/mod_ldap.so into server: /usr/lib/apache2/modules/mod_ldap.so: cannot open shared object file: No such file or directory
And of course any attempts to start apache2 after update finished
resulted in the same problem.
Solving this costed me about 15 minutes (first I thought that the ldap
module was splitted to some package), but I finally found that I
Nevertheless, this is surely the thing I could be warned before
upgrade. Also, disabling ldap module automatically is really worth
2) OK, I enabled the module above, restarted apache. Now every access
to my pages resulted in Internal Server Error, with fantasy errors
[Thu Nov 09 12:01:12 2006] [error] Internal error: pcfg_openfile() called with NULL filename
[Thu Nov 09 12:01:12 2006] [error] [client 18.104.22.168] (9)Bad file descriptor: Could not open password file: (null)
Some googling shown PLENTY of people desperately seeking for the
solution of this problem on different mailing lists and forums,
usually without any reply. Finally I found the solution, one
must add the following lines to the configuration file
3) Finally, there were no more internal errors, but my authorizations
were not accepted for some reason. I did not analyse it into detail,
but it seems 'require valid-user' no longer works. Fortunately
there is new syntax which works correctly - 'require ldap-group'.
a) during upgrade disable ldap module before stopping apache
to avoid syntax error
b) before upgrade show to the user message, warning him about
important config changes in case he is using ldap authorization
and refering him to some doc file
c) in the doc file advise him to:
- a2enmod authnz_ldap
- add clauses
in all <Location> blocks which refer to ldap authorization
- review require clauses and change require user and require group
to new require ldap-group, require ldap-user etc

Thanks for your bug report. The bug concerns the upgrade from Apache
2.0 to 2.2 but was unfortunately not fixed in time for Etch's
release. It is also not severe enough to warrant a stable update.
Therefore, the bug is not relevant anymore and I am closing it.
