Samba, Clearcase, and multiple credentials

[Frank R. Brown]

Greg -

Thanks for the info and encouragement.  Could I please ask
a couple more questions?

It sounds like I might actually end up learning something about nt
here, because I still don't get it.

First off, I don't know what a 'netlogon' is.  I do know how to connect
to shares on various specific machines, e.g., to \\hostname\ipc$.
Is a 'netlogon' something well-defined, and different than connecting
to various shares on various machines?

My understanding is that one *machine* can have at most one
connection to another *machine*.  Therefore if I'm logged on as
'user1' on 'host1', and am connected to the unix-side clearcase
server, 'server1' (let's say one machines serves everything --- vob,
views, view-private storage), as 'user1', then:

There is now *one* connection between 'host1' and 'server1'
under the credentials of 'user1', and no matter how hard it tries,
the albd service running on 'host1' will *not* be able to establish
a second connection to 'server1' with different credentials, or
otherwise access shared files on 'server1' with credentials other
than 'user1' (until the 'user1' connection is deleted).

This is the point I'm stuck on.  Is this right or wrong?

Anyway, I am going to play with the vobadm account,
and see if I can get things working.

You say albd needs to create 'cleartext' and access the
'source pools'.  Could you tell me where these beasts
normally reside?  I'd like to test by hand whether I have
access to the appropriate directories, but I'm clueless
about where to look.

Lastly, could you tell me where the clearcase mailing list
(or better still, its archives) is?

Thanks again for your help.
