Package: passwd
Version: 20000902-12woody1
Program chfn does not work as documented in its man page.
The man page says any normal user can update, for his own user account,
the "fullname" part of the GCOS field.
That is not true in Debian-Woody for the chfn command and the "fullname"
part of any normal user account GCOS field. (I don't have Debian-Sarge
here but it is trivial to try whether this bug is there too or not.)

The man page for chfn has to say "A normal user may only change the fields
for their own account, except the fullname part", or else allow the
chfn command for any user to update his own fullname information for
his own account.

On woody, the end of the chfn man page indicates that "The file,
/etc/login.defs, defines some configuration options that affects how
chfn operates, especially for non-root users."
In fact, /etc/login.defs contains a CHFN_RESTRICT variable which permits
users to change their own Full Name field (you just need to add an 'f'
there).
Note: the Sarge man page is even clearer:
"A normal user may only change the fields for her own account, subject to the
restrictions in /etc/login.defs. (The default configuration is to
prevent users from changing their fullname.)"
So I think this bug can be closed.
Best Regards
