Accessing Samba shares on external webserver(s) - how to access

Hi all,

I have recently been getting some samba shares to work on a new Solaris server.

Now that these are working (and browsable), I move on to the next hurdle!

We have a few externally hosted (Windows Server 2008 R2) web servers which are not on our domain, but can still communicate with our network.

I can successfully browse to the samba shares on the existing (soon to be retired) solaris server from these webservers.

These web servers can successfully ping the new solaris server, but I cannot browse to the shares whether I use the server name or the IP address.

I have added the new solaris server/ip address to the Hosts file on the webservers, but this has not made a difference.

Can anyone help me to access the samba shares from these WebServers?

Many thanks

I have changed the logging detail and have some further information, it looks to be an authentication problem.....

Example log when connecting as me from my PC (on the domain):

[2014/09/30 09:37:50.140615,  2] auth/auth.c:309(check_ntlm_password)
  check_ntlm_password:  authentication for user [myusername] -> [myusername] -> [myusername] succeede

Open in new window


Example log when connecting from the webserver (MYWEBSERVER) while logged on as user WEBUSER

 
check_ntlm_password:  Authentication for user [WEBUSER] -> [WEBUSER] FAILED with error NT_STATUS_NO_SUCH_USER
[2014/09/30 10:12:21.161315,  0] auth/auth_domain.c:331(domain_client_validate)
  domain_client_validate: unable to validate password for user WEBUSER in domain MYWEBSERVER to Domain controller MY.INTERNAL.DOMAIN.COM. Error was NT_STATUS_NO_SUCH_USER.
[2014/09/30 10:12:21.161877,  2] auth/auth.c:319(check_ntlm_password)
  check_ntlm_password:  Authentication for user [WEBUSER] -> [WEBUSER] FAILED with error NT_STATUS_NO_SUCH_USER

Open in new window


As I understand it, on the existing Solaris server the webservers bypass the authentication and connect to the shares as the guest user “web”.  However, this doesn’t seem to be working on the new server.

I did read about adding the line “map untrusted to domain = yes” to the smb.conf, but this doesn’t seem to have made any difference.

System authentication (where apache's user is present) is completely unrelated to samba and it's user DB.
You can always use SFTP over same SSH you have and not open security hole called samba.

I need to use Samba.

As mentioned above we have an existing Solaris server to which we can successfully browse the samba shares.  I need to replicate this on the new server.

It seems to be a problem with the guest access not working for whatever reason.

you need to copy just smb.conf and restart samba service

I have tried this, several times.  Unfortunately it does not help.

Here is my smb.conf.....

[global]
workgroup = MYDOMAIN
realm = INTERNAL.MYDOMAIN.COM
server string = Maginus SUN2014, Samba %v
interfaces = 172.16.X.X
security = ADS
password server = *
map untrusted to domain = yes
map to guest = bad password
guest account = web
server signing = auto
preferred master = Auto
wins server = 172.16.X.XX, 172.16.X.XX
idmap uid = 10000-20000
idmap gid = 10000-20000
template shell = /bin/bash
winbind enum users = Yes
winbind enum groups = Yes
# Debug logging information
log level = 2
log file = /var/log/samba.log.%m
max log size = 50
debug timestamp = yes


[home_report]
comment = Home Report for Res Bulk Pick Lists
path = /home/report
guest only = Yes
guest ok = Yes

Do you have reverse DNS working and own hostname in etc/hosts same way on both systems?

When you say 'ownhostname', do you mean the solaris hostname?  In which case I do.

How can I check reverse dns?  On the external webserver I ran ping -a 172.XX.X.X (solaris server IP) and it successfully pinged returning the server name.

This turned out to be a couple of lines in the smb.conf:

server signing = auto
preferred master = Auto

By commenting these out it solved the problem.
