WMS has standard (but optional) request GetFeatureInfo which should be implemented by most WMS servers. You do not need WFS for just object identification.

I use GetFeatureInfo early but i have only several test objects on layer. How i remember get ifo about all features from layer or its possible to get info of only one feature? – Kliver Max Nov 22 '12 at 8:02

GetFeatureInfo allows you to get attributes - in your case, the fid - of one feature, the one the user clicks on. – dariapra Nov 22 '12 at 11:26
