sudo does not accept passwds

hi i got a funny problem. sudo does not accept the passwords. i feel it is because of the md5. i'm using 6.3 and it worked fine till i md5'd the passwd. i tried it on a redhat comp , still it didn't work. what is the problem ? how do i make it work ? i got major problems. right now, i've given NOPASSWD for all in the sudoers . please hlep. thanx in advance cheedu -- ***** cogito cogito ergo cogito sum: i think that i think, therefore i think that i am. --Devils Dictionary --
