I get a lot of these messages in logfile:
[2014/12/15 13:48:54.172689, 0, pid=2950] ../source3/libads/kerberos.c:926(create_local_private_krb5_conf_for_domain)
create_local_private_krb5_conf_for_domain: smb_mkstemp failed, for file /var/cache/samba/smb_tmp_krb5.wgU6ix. Errno Permission denied
checking the owner of pid 2950:
fileserv:/var/cache/samba# ps axwu|grep 2950
root 2950 0.1 1.1 37056 11476 ? S 08:33 0:27 /usr/sbin/smbd -D
checking permissions of the directory:
ls -ld /var/cache/samba
drwxr-xr-x 4 root root 4096 Dez 15 14:23 /var/cache/samba
checking if the file already exists:
/var/cache/samba/smb_tmp_krb5.wgU6ix: No such file or directory
checking that there are no strange ACL entries:
getfacl -s /var/cache/samba
--> no output.
when i do chmod 777 /var/cache/samba, the problems will go away, but testparm will comply that permissions need to be 755. when setting the permissions back to 755 the problems will be there again.
i have no selinux and no apparmor running.
i do not understand the problem. how can i help to debug here?
this is not a generic issue, if you still see this kind of problem in your setup, you might consider to consult support from https://www.samba.org/samba/support/globalsupport.html
