The last caller was removed in samba-tool: Remove C version of samba-tool
(e2af384151) by Amitay Isaacs in 2011
This was a tool to dump a genine NT4 DC (never Samba) into smbpasswd file.
It did work against Windows AD, but DRS replication is much
more comprehensive.

/*! \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
