[webmin-l] Change Password error

[Dave I. <dav...@en...>]

Previously, when I was using the Webmin 1.230 (on RedHat EL3) passwd module,
there were no problems.
 
Now, using the Webmin 1.250 version, I get the error "Failed to change
password : Failed to encrypt password :".
 
Looking at web-funcs-lib.pl, at the unix_crypt() subroutine, I can see that
if the call to crypt() fails, then Crypt::UnixCrypt is used instead.
Indeed, in my case the 
 
$rv = eval "crypt(\$pass, \$salt)";
 
call is resulting in $rv being undef.  The fallback to Crypt::UnixCrypt does
not work because I do not have that perl module installed.
 
Now my question is: why is the call to crypt() failing?  It was not failing
previously.  Doing a little digging, I discovered the when the failure
occurs, $pass is equal to the old password and $salt is equal to undef.
Without salt, crypt() appears to return nothing.  Why is the salt undef?
 
Thanks
