HP-UX has similiar concept in SAM but I've never used it. All versions of unix have suid programs which is why sudo can work.

grpconv

PWCONV(8)						      System Manager's Manual							 PWCONV(8)

NAME

       pwconv, pwunconv, grpconv, grpunconv - convert to and from shadow passwords and groups.

SYNOPSIS

       pwconv
       pwunconv
       grpconv
       grpunconv

DESCRIPTION

       These four programs all operate on the normal and shadow password and group files: /etc/passwd, /etc/group, /etc/shadow, and /etc/gshadow.

       pwconv  creates	shadow	from  passwd  and  an optionally existing shadow.  pwunconv creates passwd from passwd and shadow and then removes
       shadow.	grpconv creates gshadow from group and an optionally existing gshadow.	grpunconv creates group from group and	gshadow  and  then
       removes gshadow.

       Each program acquires the necessary locks before conversion.

       pwconv  and  grpconv  are  similiar.   First,  entries in the shadowed file which don't exist in the main file are removed.  Then, shadowed
       entries which don't have `x' as the password in the main file are updated.  Any missing shadowed entries are added.  Finally, passwords	in
       the  main  file	are  replaced with `x'.  These programs can be used for initial conversion as well to update the shadowed file if the main
       file is edited by hand.

       pwconv will use the values of PASS_MIN_DAYS, PASS_MAX_DAYS, and PASS_WARN_AGE from /etc/login.defs when adding new entries to /etc/shadow.

       Likewise, pwunconv and grpunconv are similiar.  Passwords in the main file are updated from the shadowed file.  Entries which exist in  the
       main file but not in the shadowed file are left alone.  Finally, the shadowed file is removed.

       Some password aging information is lost by pwunconv.  It will convert what it can.

BUGS

       Errors  in  the	password  or  group files (such as invalid or duplicate entries) may cause these programs to loop forever or fail in other
       strange ways.  Please run pwck and grpck to correct any such errors before converting to or from shadow passwords or groups.
