Subject: Solaris 10 "cp -p" returns unknown error on NFSv4 share,permissions
	preserve not work
Date: Wed, 26 Sep 2012 14:16:39 +0200

Hello,

i want to report bug in coreutils 8.19 observed on Solaris 10 update 9 and 10 on i386 and sparc platforms(i386-Generic_147441-07/sparc-Generic_147440-07). 
Copy preserve does not work on NFSv4 share and omit permissions. "Unknown system error" returned. Files have no acls set.

Way to reproduce:
-rwxr--r--   1 myuser  mygroup           0 Sep 26 12:47 test1

myuser <at> testbox:~$ /opt/gsb/bin/cp -p test1 test2
/opt/gsb/bin/cp: 'test1': Unknown system error

myuser <at> testbos:~$ ls -l test2

Expected result:
-rwxr--r--   1 myuser  mygroup           0 Sep 26 12:47 test2

Actual result:
-rwx------   1 myuser  mygroup           0 Sep 26 12:47 test2


Some truss output show me problem with acl calls:

truss cp -p test1 test2

Coreutils compiled with "--without-gmp". Compiled with Oracle Studio 12.3 and tested with gcc 3.4.3 too.

Described problem above does not occur when coreutils are compiled with "--disable-acl" configure option.
