Re: [webmin-l] Change Password error

Hi Dave,
That looks like a bug in Webmin.
Which module are you doing the password change in though? It seems that the caller of unix_crypt is passing in the wrong parameters.

    Previously,  whenI 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
