so here it is the code to introduce seriously debugggging classes.
this is a first step only passdb stuff has beein "classized". - so what can you do? set debug level to: 1 poasdb:10 that will make all the code run at debug level 1 except the code in passdb/* files that will run at level 10 TODO: fix the man page - also smbcontrol has this nice feature so smbcontrol smbd debug 3 passdb:5 will set every smbd to have a default log level of 3 while passdb stuff will be at level 5 and so no.. minor cosmetic fix to pdbedit is there too (This used to be commit be5c3b3f5781ddc002ffcc98df04ab024dcef4ca)
