2d41bcce83 selftest/drs: Demonstrate ERROR(ldb): uncaught exception - Deleted target CN=NTDS Settings... in join
"samba-tool domain join" uses the replication API in a strange way, perhaps no longer
required, except that we often still have folks upgrading from very old Samba versions.

By deferring the writing out to the DB of link replication to the very end, we have a
better chance that all the objects required are present, however the situation may
have changed during the cycle, and a link could still be sent, pointing to a deleted
object.

We currently fail in this situation.

234957a2e4 Fix build after removal of an extra safe_string.h
Move of strcasecmp redefine to lib/util/safe_string.h in
https://gitlab.com/samba-team/samba/-/merge_requests/1507 broke build on
Fedora 33 with GCC 10.2.1 for those compilation units that use
ldb_att_cmp().

The reason for that is that ldb_attr_cmp() defined as

   #define ldb_attr_cmp(a, b) strcasecmp(a, b)

because attribute names restricted to be ASCII by RFC2251 (LDAPv3 spec).

A solution is to add

   #undef strcasecmp

to all source code files which use ldb_attr_cmp().

e075f52a75 pyldb: fork pyldb_Ldb_AsLdbContext macro to reflect unsafeness
In the Python/C API, conversion functions which check the types of their arguments
have names like:

double PyFloat_AsDouble(PyObject *pyfloat);

while conversion macros that don't check have names like:

PyFloat_AS_DOUBLE(pyfloat)

The pyldb_Ldb_AsLdbContext() macro looks like one of the checking functions
but it actually isn't. This has fooled us more than once. Here we fork
the macro into two -- one which performs checks and keeps the camel
case, and one with a shouty name that keeps the check-free behaviour.

22208f52e6 dbchecker: Fixing up incorrect DNs wasn't working
dbcheck would fail to fix up attributes where the extended DN's GUID is
correct, but the DN itself is incorrect. The code failed attempting to
remove the old/incorrect DN, e.g.

 NOTE: old (due to rename or delete) DN string component for
 objectCategory in object CN=alice,CN=Users,DC=samba,DC=example,DC=com -
 <GUID=7bfdf9d8-62f9-420c-8a71-e3d3e931c91e>;
   CN=Person,CN=Schema,CN=Configuration,DC=samba,DC=bad,DC=com
 Change DN to <GUID=7bfdf9d8-62f9-420c-8a71-e3d3e931c91e>;
   CN=Person,CN=Schema,CN=Configuration,DC=samba,DC=example,DC=com?
 [y/N/all/none] y
 Failed to fix old DN string on attribute objectCategory : (16,
 "attribute 'objectCategory': no matching attribute value while deleting
 attribute on 'CN=alice,CN=Users,DC=samba,DC=example,DC=com'")

The problem was the LDB message specified the value to delete with its
full DN, including the GUID. The LDB code then helpfully corrected this
value on the way through, so that the DN got updated to reflect the
correct DN (i.e. 'DC=example,DC=com') of the object matching that GUID,
rather than the incorrect DN (i.e. 'DC=bad,DC=com') that we were trying
to remove. Because the requested value and the existing DB value didn't
match, the operation failed.

We can avoid this problem by passing down just the DN (not the extended
DN) of the value we want to delete. Without the GUID portion of the DN,
the LDB code will no longer try to correct it on the way through, and
the dbcheck operation will succeed.

5055b54d4a s4/dsdb: Additionally accept unicode as string param in Py2
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)
