[Samba] Anybody got any ideas as to how to fix this problem? -- on both 3.0.5 and 3.0.6 PDC

[M. D. Parker]

I previously reported a problem where I was seeing all sorts of Interrupted
system call errors for the /etc/samba/smbpasswd file.  This caused some
significant temporary problems at our site in user validations.

Seems upon analysis of the various log material, and coding.....that the
Interrupted system call is legit.  It is simply indicating a timeout for the
lock request on the /etc/samba/smbpasswd file which really should not happen
but it does.

OK, in checking the system further, we find one system basically constantly
holding open / or using the passwd file for authentication for some reason
thus causing the other clients to become basically locked out.

This client has the following log entries:

====================

NOTE: Both the machine and client smbpasswd entries are of the "NEW" type as
noted by the number of fields in each entry:

client$:753:XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX:BDCCBA58CAE2136EE5F68206ADC748E
A:[W         ]:LCT-40F2BF93:

username:962:A8AD058EA120084B1486235A2333E4D2:11D4C351D6C291170C2D6192EB8E99
FC:[U          ]:LCT-41360DED:

Further entries in the /etc/passwd and /etc/shadow file track correctly to
the information in the samba passwd file.
I'm not sure any changes are being made here as our site (by directive
unfortunately) so I do not understand what would be changing either.

What problem are we seeing?  Any ideas what to do to fix this?
