The other day I asked how to solve the problem where my NT domain username
is <PHILIPH> and my samba username is <philip>. Several replied
indicating the "username map" option in smb.conf (can't believe I
missed
it). Anyway, by adding the following line to smb.conf:
usrname map = /path/to/username.map.file
and then adding the following line to the above referenced file:
philip = philiph
I can no log into samba specifying my samba password and it works.
I've copied the username map description from smb.conf.
Thanks to all those who responded!
-philip

username map (G)
This option allows you to to specify a file containing a
mapping of usernames from the clients to the server. This
can be used for several purposes. The most common is to map
usernames that users use on DOS or Windows machines to those
that the UNIX box uses. The other is to map multiple users
to a single username so that they can more easily share
files.
The map file is parsed line by line. Each line should con-
tain a single UNIX username on the left then a '=' followed
by a list of usernames on the right. The list of usernames
on the right may contain names of the form @group in which
case they will match any UNIX username in that group. The
special client name '*' is a wildcard and matches any name.
Each line of the map file may be up to 1023 characters long.
The file is processed on each line by taking the supplied
username and comparing it with each username on the right
hand side of the '=' signs. If the supplied name matches any
of the names on the right hand side then it is replaced with
the name on the left. Processing then continues with the
next line.
If any line begins with a '#' or a ';' then it is ignored
If any line begins with an ! then the processing will stop
after that line if a mapping was done by the line. Otherwise
mapping continues with every line being processed. Using !
is most useful when you have a wildcard mapping line later
in the file.
For example to map from the name "admin" or
"administrator"
to the UNIX name "root" you would use
root = admin administrator
Or to map anyone in the UNIX group "system" to the UNIX name
"sys" you would use
sys = @system
You can have as many mappings as you like in a username map
file.
If Samba has been compiled with the -DNETGROUP compile
option then the netgroup database is checked before the
/etc/group database for matching groups.
You can map Windows usernames that have spaces in them by
using double quotes around the name. For example:
tridge = "Andrew Tridgell"
would map the windows username "Andrew Tridgell" to the unix
username tridge.
The following example would map mary and fred to the unix
user sys, and map the rest to guest. Note the use of the !
to tell Samba to stop processing if it gets a match on that
line.
!sys = mary fred guest = *
Note that the remapping is applied to all occurrences of
usernames. Thus if you connect to "\\server\fred" and
"fred"
is remapped to "mary" then you will actually be connecting
to "\\server\mary" and will need to supply a password
suitable for "mary" not "fred". The only exception to
this
is the username passed to the "password server" (if you have
one). The password server will receive whatever username the
client supplies without modification.
Also note that no reverse mapping is done. The main effect
this has is with printing. Users who have been mapped may
have trouble deleting print jobs as PrintManager under WfWg
will think they don't own the print job.
Default no username map
Example username map = /usr/local/samba/lib/users.map
