I thought the relative dearth of critical bug reports so far was too good to be true :-) Sounds like I have introduced a bug into `pwd_mkdb -u', which is the common denominator in your reports. `passwd', `chsh', `pw' all use `pwd_mkdb -u', whereas vipw uses plain `pwd_mkdb'. I will look at it closely today! Meanwhile, if this happens to you, just run `vipw' or `pwd_mkdb' to rebuild your database. Cheers, -- Jacques Vidrine . NTT/Verio SME . FreeBSD UNIX .
