While ldap_get_entries_moodle() PHPdocs state that it returns "array
ldap-entries with lower-cased attributes as indexes.", this is not true. It
uses ldap_get_attributes() internally, which returns both numerically indexed
attribute names, and dictionary-like entries indexed by attribute names.
Current code lowercases the dictionary-like entries, but then uses the
numerically indexed entries for the attribute names used as keys in the
returned array. The numerically indexed names might or might not be lowercased,
depending on the LDAP server and PHP version) version. E.g., OpenLDAP 2.x,
Novell eDirectory 8.x and MS Active Directory return mixed-cased attribute
names, and PHP 5.x and PHP 7.x don't lowercase them inside ldap_get_entries().
This is probably why all calls to ldap_get_entries_moodle() are followed by
calls to array_change_key_case(), even if that shouldn't be necessary.
So make sure we always return lower-cased attributs as indexes and add some
unit tests to avoid regressions in the future.
There is at least one LDAP server (Sun Directory Server) that doesn't
support Paged Results extension, even if it supports LDAP version 3. So
checking just for LDAP version is not enough.
If possible, we check the supportedControl attribute of the LDAP rootDSE
and see if the paged results control is available. This needs an LDAP
connection, which might not be possible to establish before we configure
some essential LDAP settings (server, bind user, password, etc.). Thus
we try to establish the connection and check the supportedControl
attribute. But if we fail, we perform only basic checks that are less
accurate and err on the side of cautiousness.
While testing the fix, it was found that ldap_stripslashes() was broken and
using a deprecated PCRE patter modifier, so it's also been fixed.
Thanks to Damyon Wiese, some units tests have been added to cover
ldap_addslashes() and ldap_stripslashes().
MDL-41304 only fixed the case when 'Search subcontext' is enabled. We need to
fix the case when it's not enabled too.
While silencing errors with an @ should be avoided if possible, there's no
other way to prevent the warnings in this case.
We need to specify a valid user id in the call to role_assign(). And we only
have to make the call if the user has been added successfully, not
otherwise.
Also make sure we lowercase the memberuser and group distinguished names
before comparing them. Depending on the LDAP server we can get mixed case
values for the DNs, and the user may have specified the creators group/ou
name in a different case.
By the way, this has been broken for ages (since the auth cleanup in 1.8, in
2007!). It's a bit strange nobody noticed before :-O
Credit goes to Joe Chryst.
We've moved some of the LDAP auth plugin "knowledge" of different LDAP
servers to a common library, and we've added support for nested groups
enrolments for selected LDAP servers.
Lots of changes in the language pack, as all the plugin messages have been
internationali[sz]ed (it also includes renaming of quite a few string
identifiers).
During plugin settings migration, we rename 'version' setting to
'ldap_version', as we store the plugin version itself as a setting in the
plugin config table and the two collided.
Performance is not great for larga data sets but this can be improved later
(20000 users, 4000 courses and 100 users/course take around 1h25m on a somewhat
tuned postgresql-8.4 on a 2.66GHz Core2 Duo w/ 4 GB of RAM).
