I'm not understanding the use of openafs on the samba server. Are you tryin=
g
to store windows profiles through a samba share that actually is pointing t=
o
storage in AFS? This implies that you must pass security info clear text to
samba in order to get an afs token for the user on the windows box, and the=
n
doing some kind of pass through samba to store the file in afs. This just
sounds way too wrong.

<pre>The afslogon.dll has special code in it that has to detect t=

would have to be added.

<pre>Just an idea... why don't put an option inside the AFS con=
trol panel to
override the domain detection ? Not all the users using a roaming
profile use a Domain.... Something like "roaming profile active" =
in the
AFS control panel....
Anyway, now how i can override that detection of the afslogon.dll ? Any
trick to cheat the afslogon.dll auto detection?
Cordially,

<pre>Claudio:
It would be more work to implement a cheat than to do the correct thing
for your configuration. Someone can write a patch for afslogon and
submit it to <a href=3D"http://gerrit.openafs.org" target=3D"_blank">gerrit=
.openafs.org</a>.
What needs to be implemented is the Local Profile in AFS case both for
NPLogonNotify() and AFS_Logoff_Event(). If the profile is not remote,
then a search for a profile in AFS should not be queried via AD (LDAP)
but instead through the GetUserProfileDirectory() API.
If you read the OpenAFS for Windows Release Notes, you can use the
LogoffPreserveTokens registry value to force the AFS tokens to be held
after logoff. However, doing so retains the tokens until they expire.

<pre>Sorry if that sounds stupid, but are currently the NPLogonNotify()=
and
AFS_Logoff_Event() calls querry AD via LDAP? If so I suppose they aren'=
t
discovering a pre-AD (NT4, Samba3) redirected domain profile either?
I've just planned to move the user profiles of our Samba3 domain to AFS=
:-(.
