Title:
  Insufficient access in dyndb DEP8 test

Status in bind-dyndb-ldap package in Ubuntu:
  In Progress
Status in bind9 package in Ubuntu:
  In Progress

Bug description:
  Caught this in a run of the dyndb-ldap DEP8 test:

  280s 2023-09-05T00:59:05.435102+00:00 autopkgtest slapd[1491]: conn=1010 op=1 MOD dn="idnsName=example.internal,ou=dns,dc=example,dc=internal"

  280s 2023-09-05T00:59:05.436068+00:00 autopkgtest named[1519]: LDAP error: Insufficient access: while modifying(replace) entry 'idnsName=example.internal,ou=dns,dc=example,dc=internal'

  Looks like sometimes the dyndb-ldap plugin wants to write to the tree,
  and not just read from it. Looking at the code, that can happen for
  some SOA attributes, and perhaps other cases too. The documentation
  isn't immediately clear.

  A re-run of this test cleared the error, but we all dislike flaky
  tests, so it's probably best to adjust the ACL and allow the bind9
  user to write to the DNS tree. Production deployments will definitely
  want to fine tune this ACL and list explicit attribites and entry
  types that can be modified, but for a DEP8 test, this is enough.
