Can't use string (Domain) as an ARRAY ref while "strict refs" in use

Hello All,

First off, thanks for your help. I am not EXACTLY sure that LdapContrib is the problem, however, it may point to the issue due to the logs I'm getting.

Here's what happened. I was running LdapContrib 4.2x with templatelogin with no issues this morning, and noticed there was an upgrade to 5, so I dove in head first. I've always had good luck with Mr. Daum's software, so what the hell.

After all the patches were complete and up and running, I logged out of the website I get this error on front webpage:

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

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

I enabled LDAP debug and tried the front page again:

So, it seems there's a larger problem at hand here, and I've googled this one to death and can't find anything related to strict refs anywhere. I just keep coming back up with the LdapContrib.Pm file, however I'm not prepared to edit that, because I don't have any perl skills.

So, I'm sure all of you out in Foswiki support land would love to see my LdapContrib config:

Foswiki::cfg{Ldap}{Host} = 'x.x.x.x';
$Foswiki::cfg{Ldap}{Port} = 389;

$Foswiki::cfg{Ldap}{RewriteGroups} = {
          '(my admin group)' => 'AdminGroup',
          '(my admin group)' => 'AdminGroup',
          '(my admin group)' => 'AdminGroup',
          '(my admin group)' => 'AdminGroup'
        };
$Foswiki::cfg{Ldap}{RewriteWikiNames} = {};
$Foswiki::cfg{Ldap}{MergeGroups} = 0;
$Foswiki::cfg{Ldap}{MaxCacheAge} = '86400';
$Foswiki::cfg{Ldap}{Precache} = 1;
$Foswiki::cfg{Ldap}{PageSize} = 500;
$Foswiki::cfg{Ldap}{Exclude} = 'WikiGuest, ProjectContributor, RegistrationAgent, UnknownUser, AdminGroup, NobodyGroup, AdminUser, admin, guest';

If you need any more information from my LocalSite.cfg, just let me know.

Again, thank you for your help.

Apply these changes to your config:

$Foswiki::cfg{Ldap}{UserBase} = ['dc=my domain,dc=local'];
$Foswiki::cfg{Ldap}{GroupBase} = ['DC=my domain,DC=local'];

Note the square brackets.

That worked! Thanks for the quick follow up Michael!

Matt, which version of LdapContrib did you use?

-- MichaelDaum - 07 Dec 2012

Michael, I'm currently running the current version of 5.03.
