Convert second param passed to ldb.Dn to be unicode so py2 & py3 code
will work
Signed-off-by: Noel Power <noel.power@suse.com>
Reviewed-by: Alexander Bokovoy <ab@samba.org>
With the changes to make samba python code Py2/Py3 compatible there
now are many instances where string content is decoded.
Decoded string variables in Py2 are returned as the unicode type. Many
Py2 c-module functions that take string arguments only check for the
string type. However now it's quite possibe the content formally passed
as a string argument is now passed as unicode after being decoded,
such arguments are rejected and code can fail subtly. This only affects
places where the type is directly checked e.g. via PyStr_Check etc.
arguments that are parsed by ParseTuple* functions generally already
accept both string and unicode (if 's', 'z', 's*' format specifiers
are used)

We have to also take it out in the partitions code when we load the
partition backends.
This ensures that the init handlers hold a whole-db lock just as the
search code does.
To ensure the locking count in schema_load is balanced, the
private data is now created in the first lock_read() call.

Note there's no msDS-ServiceAccount in any schema (only

This change ensures we correctly treat the following LDIF

one, the ACL module wrongly treated this as a password change
request.
For a password change we need at least one value to delete and one value
to add. This patch ensures we correctly check attributes and their
values.
