Question

Relative to the LdapContrib Plugin, how do we default the “$TWiki::cfg{Ldap}{MaxCacheAge}” value to infinite, so that it never updates the cache. This value is under ‘Performance settings’ (Maximum time a cache is kept; default is 86400 seconds)

To disable automatic cache aging you have to set it to 0:

$TWiki::cfg{Ldap}{MaxCacheAge} = 0;

That is exactly what we have set; unfortunately, it is not having the desired effect.

So even after setting your MaxCacheAge to 0, your cache is still updated daily? Which TWiki version and LdapContrib version are you using?

-- MartinKaufmann - 13 Feb 2008

We are using TWiki v4.2.0 and LdapContrib v2.99.3; and yes, our cache updates daily, and at random times, despite our setting the MaxCacheAge to 0.

I don't know enough about LdapContrib internals (to be honest, I don't know anything at all...) but it might be best to raise a bug.

If you just want to make sure that the cache is never updated automatically and don't mind hacking the perl code, just uncomment the following line (should be about line 568) of lib/TWiki/Contrib/LdapContrib.pm:

$this->refreshCache();

I can confirm this bug. Filed as Bugs:Item5365, also reported at DisableLdapContribBuildingOfOwnCache. Will be fixed in next release.
