Here is my smb.conf
===================================================================
[global]
workgroup = AD
realm = AD.COLORADO.EDU
password server = dc11.ad.colorado.edu dc12.ad.colorado.edu
security = ads

winbind separator = +
idmap config AD:readonly = yes

encrypt passwords = yes
passdb backend = smbpasswd

hosts allow = 128.138.

log level =  10
log file = /var/log/samba/log.%m

# Put a capping on the size of the log files (in Kb).
#   max log size = 50

[homes]
        guest ok = no
        writeable = yes

[tmp]
        path = /tmp
        writeable = yes
================================================================

when I log in with smbclient it logs in fine and authenticates via the ad properly and it maps my UID properly fine but I cannot remove or rename files. Altough I am able to upload files.

The contents of log.moxz (moxz is the machine name) when I login is in the attachment called "log.login"

the contents of the same file (log.moxz) when I try to rename the file is in the attachment called "log.rename"

and here are it looks like from the command line
===================================================================
moxz:~>ls -l k
-rwxr--r-- 1 elatov pitserver 54 Jul 24 08:10 k

moxz:~>getent passwd elatov
elatov:x:17227:150:Karim Elatov,,, :/home/pitserver/elatov:/bin/tcsh

moxz:~>smbclient //moxz/elatov
Enter elatov's password: 
Domain=[AD] OS=[Unix] Server=[Samba 3.4.0]
smb: \> rename k j
NT_STATUS_ACCESS_DENIED renaming files \k -> \j 
=================================================================

If I do the same thing with on the /tmp share then it works fine it looks like this
=================================================
moxz:~>ls -l /tmp/a
-rwxr-xr-x 1 elatov pitserver 165 Jul 25 13:29 /tmp/a

moxz:~>smbclient //moxz/tmp
Enter elatov's password: 
Domain=[AD] OS=[Unix] Server=[Samba 3.4.0]
smb: \> rename a b
smb: \
======================================================================

as you can see no error was produced.

here is the info about my machine
===========================================
moxz:~>uname -X
System = SunOS
Node = moxz.colorado.edu
Release = 5.10
KernelID = Generic_141415-05
Machine = i86pc
BusType = <unknown>
Serial = <unknown>
Users = <unknown>
OEM# = 0
Origin# = 1
NumCPU = 
============================

I am really stumped as to why the ad mapping is properly getting set but yet I get an "access denied error".

Any help is much appreciated.
Thanks
