Hello List, First off this is my first posting to the list having joined yesterday so if I'm doing something wrong I'll apologise now! Secondly I've just been asked to add some Linux workstations to our existing RM Connect 2.3 network, I thought that I could use winbind to authenticate users to our PDC rather than add a whole load of new usernames and passwords to each Linux workstation. Unfortunately my attempts so far have been unsucessfull, my current problem is that winbind complains that 'user [domain]+[username] not known to underlying authentication module' and resets. Having searched the archives it appears that some people have this setup working but I can't find out how they did it! Any suggestions received with thanks. Tim Neale Kingsdown School, Swindon
