If you used ldap before, make sure to remove (or comment out) all the settings for that feature. If you decide to keep the old settings and add the new ones, the old ones are preventing DokuWiki to connect to the LDAP server properly (as I just noticed — Werner Flamme 2013/02/18 08:54).

I guess this should not interferer. If i read the code correct first the default are loaded, next the old auth settings and next the new auth settings. So it should not interfere? Maybe better to ask him examples.
