SID-02043: Logging failing - perl error

Status:	Answered	TWiki version:	6.0.1	Perl version:	v5.18.2 - built for x86_64-linux-gnu-thread-multi
Category:	LdapContrib	Server OS:	Ubuntu 14.04.2 LTS	Last update:	10 years ago

When trying to login, I receive the following error message:

TWiki detected an internal error - please check your TWiki logs and webserver logs for more information.

Can't use string ("ou=groups,dc=domain,dc=org") as an ARRAY ref while "strict refs" in use

• bin/configure {Ldap}{GroupBase}:

  'ou=groups,dc=domain,dc=org'

• twiki/lib/LocateSite.cfg:

  $TWiki::cfg{Ldap}{GroupBase} = 'ou=groups,dc=domain,dc=org';

Using the predefined notatation:

[
    'ou=groups,dc=52north,dc=org'
]

After updating twiki/tools/ldaptest with the same configuration values, the test tools was able to connect to the remote LDAP server and retrieve values.

The log output looks like:

What is needed to get authentication against the remote LDAP running? Do you need any additional information?

Discussion and Answer

If you have write access to LocalSite.cfg, try entering the value like this:

$TWiki::cfg{Ldap}{GroupBase} = ['ou=groups,dc=domain,dc=org'];

This is identical to the syntax shown in configure, so I don't have a good clue why this doesn't work for you (but I don't have any clue about LdapPlugin either). Maybe the config values are only read on startup and won't take effect unless you restart the web server? But I guess you've already tried this...
