+/*! \file lib/smbpasswd.c
+
+   The smbpasswd file is used to store encrypted passwords in a similar
+   fashion to the /etc/passwd file.  The format is colon separated fields
+   with one user per line like so:
+
+   <username>:<uid>:<lanman hash>:<nt hash>:<acb info>:<last change time>
+
+   The username and uid must correspond to an entry in the /etc/passwd
+   file.  The lanman and nt password hashes are 32 hex digits corresponding
+   to the 16-byte lanman and nt hashes respectively.  
+
+   The password last change time is stored as a string of the format
+   LCD-<change time> where the change time is expressed as an 
+
+   'N'    No password
+   'D'    Disabled
+   'H'    Homedir required
+   'T'    Temp account.
+   'U'    User account (normal) 
+   'M'    MNS logon user account - what is this ? 
+   'W'    Workstation account
+   'S'    Server account 
+   'L'    Locked account
+   'X'    No Xpiry on password 
+   'I'    Interdomain trust account
