Last friday we upgraded from 1.9.17p4 to version 1.9.18p3 on a HP-UX 9.04 machine. Now we get lots of entries in the log.smb file like: ERROR: del_share_mode: failed to ftruncate share mode file /programs/samba/var/locks/share.1073807365.8199 to size 42 (Permission denied) ERROR: set_share_mode: failed to ftruncate share mode file /programs/samba/var/locks/share.1073807365.8195 to size 42

...he problem in dmapi_file_flags() is that things are running with the effective uid of the user, so dmapi calls are failing. The posix capability DMAPI_ACCESS_CAPABILITY is supposed to allow the functions to work, but to my knowledge AIX doesn't have posix capabilties. I used become_root/unbecome_root around the dmapi calls, and this appeared to get things to work. Samba's log messages are indicating that files are offline, and Windows Explorer is picking up on this and changing the file icons to indicate that the files are offline. However, I don't know if my solution is entirely c...

It's exactly the same. Except that I use tdbsam instead of ldap and the error message therefore also is different in the log file. But the example and result is the same.
