hi, earlier i tried with literal "AAAAAA", which was probably not what you meant. it produced a "not found". using an affected user name yields (with both your programs): getpwnam_r: Invalid argument while an existing shell account yields its UID: Name: ; UID: 1001 for me its not clear whats the difference between a literal AAAA string and an existing username not in passwd (why one produces an error and one doesnt). sorry for not reading carefully earlier… georg
