Re: [Samba] Roaming Profiles -- Problem Rapidly Switching Users

2005-01-25 Thread Thomas Reiss 
Hallo [EMAIL PROTECTED], 

 
 If I just wait about 3 or 4 minutes, however, I can log on again as any user 
 and access the roaming profile. 

Maybe a Timesync Problem between Samba Server and Windows Client ?
Can you pleas check this ?

[Samba] Roaming Profiles -- Problem Rapidly Switching Users

2005-01-24 Thread AndyLiebman 
Does anybody have any insight into what could be causing this strange 
problem? I have Samba 3.02 (sorry, can't upgrade right now). My Linux box is 
running 
Mandrake 10 Official. I have Samba configured as a PDC. 

I can successfully add machines to my Domain -- and log on as ANY user from 
ANY machine. However on a SINGLE MACHINE, when I log on as USER_1 and access 
that user's roaming profile, if I then log off and immediately try to log on 
again (AS USER_1 or ANOTHER USER), Windows XP gives me a message saying that it 
can't access the user's roaming profile and that maybe there's a problem with 
permissions. 

If I just wait about 3 or 4 minutes, however, I can log on again as any user 
and access the roaming profile. 

Looking at the profile directory on my Linux Box, and can see that the 
roaming profile is updated when I succeed in accessing the roaming profile. 
When I 
get that message, Windows just uses the last information that was stored 
locally on the computer. 

The cause doesn' t seem to be a problem with permissions. As I log on and log 
off, I am watching the permissions on the profiles directory and they are 
not being altered. 

And I don't see anything in /var/log/samba/[machine_name].log that looks 
suspicious, except an occasional message: [machine_name] (192.168.1.101) 
couldn't 
find service [user who was trying to log on]. 

BTW, I have my profiles directory in the following path:
/home/bigboss/profile/

The home directory on this machine is actually on its own very large 
partition -- so it's a good place to put the profiles. Whereas the root 
partition / 
has much less space -- certainly not adequate for 200 users with roaming 
profiles. 

I tried putting the profiles in /home/profile -- but every time I rebooted 
the permissions of the permissions of the profile directory would get changed 
to read-only for the group that needs to access the directory. 

Any ideas or solutions?

Re: [Samba] Roaming Profiles -- Problem Rapidly Switching Users

2005-01-24 Thread AndyLiebman 
Here is the log from /var/log/samba/[machine name].log. It seems to imply that 
it takes Samba about a minute to finish closing all the connections for the 
user who just logged out on a machine -- and therefore a new user can't log on 
and access his/her roaming profiles until the logging out/closing connections 
and services has been completed. 


This is when I am able to log on with a roaming profile:

Below is where I COULD NOT log on with roaming profiles. I'm not sure whether 
the last line above goes with logging off or logging on.

Am I to conclude from these logs that it takes Samba about a minute or so to 
finish logging off the current user from a machine, and that you can't log on 
as the next user for about one or two minutes? 

That is my observation. If I wait for two minutes, no problem logging back on, 
or logging on as a different user. Wait only 30 seconds, it doesn't. Waiting 
some time between, I'm not sure what works and what doesn't.
