Bit of a strange on this.
I have a user running 3.2.1 from a Linux box and in the apache config file I've used ldap authentication just to add another layer.
Now it works fine from his PC but from his phone, well I quote:
"The double log-in for WordPress seems to be causing a problem with my Nokia WordPress application but not with the equivalent for the iPad or with a normal computer working through the browser, so let's leave it as it is as it is for now. Maybe reinstalling the app on the Nokia will solve the problem."
I don't have a Nokia so does anyone have any idea about what causes this?
