-/*! \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
