Thanks for pointing this out (I actually missed the BR in LP, even
though I receive these bug reports).

Brynnen Owen mentioned this to us, recently, indeed.

The fix has been committed in the Debian package SVN. It will reach
Debian unstable, then Ubuntu, when we upload a new release.

Given that the fix is trivial but has important consequences for
anybody wanting to use the TDB2 backend, I'll ask for permission to
upload a fix in squeeze too.

Title:
  tdb2.so undefined symbol: dyn_get_STATEDIR (source code typo)

Status in “samba” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: samba

  This error occurs if "idmap backend = tdb2" is specified in smb.conf

  The source of the error is this patchfile
  fhs-filespath.patch

  The offending patch is at the bottom of the file, as follows

  ===================================================================
  --- a/source3/winbindd/idmap_tdb2.c
  +++ b/source3/winbindd/idmap_tdb2.c
  @@ -107,7 +107,7 @@
   	if (db_path == NULL) {
   		/* fall back to the private directory, which, despite
   		   its name, is usually on shared storage */
  -		db_path = talloc_asprintf(NULL, "%s/idmap2.tdb", lp_private_dir());
  +		db_path = talloc_asprintf(NULL, "%s/idmap2.tdb", dyn_get_STATEDIR());
   	}
   	NT_STATUS_HAVE_NO_MEMORY(db_path);

  The correct function name is get_dyn_STATEDIR, not dyn_get_STATEDIR.

  I've tested it can be fixed by changing this accordingly.
