I was able to su to a user with a shell of '/bin/false' successfully and continue working with the new users permissions. Does the shell even get changed after an 'su'? I got the Perl script working great. And was even inspired by it to do a 'man crypt'! Which immediately brought to mind another 1/2 dozen questions... but I'd better stick with the task at hand for now. The 'checkpassword' program that I downloaded seems to be more of a utility to use in conjunction with other programs such as POP toasters that need to access user accounts. > >"su" won't work if their shell is /bin/false. > > > Why wouldn't su work for verifying a password ?
