Comment 15 for bug 1978849

The focal situation explained in the last comments above is still more complicated than originally thought. Looks like bind-dyndb-ldap never really worked in focal.

Some options:
a) fire up gdb, and see where exactly it's failing. It could be a symbol clash, an incorrect library being linked in, just incompatible code, or something else;
b) backport a new bind-dyndb-ldap version what works with bind9 9.16.x as shipped in focal. The problem is that src:bind9 in focal does not provide a dev package, so where are no header files nor development libraries to link with. A new binary package built from src:bind9 in focal would have to be created, like bin:bind9-dev that exists in jammy and later.

Given the above, and the fact that there is another LTS where bind-dyndb-ldap works (after this update here in the bug), we think it's not worth it to attempt to fix bind-dyndb-ldap for focal.

If the situation changes (perhaps a patch becomes available, or another solution different from (a) and (b) above, or there is a strong demand to have this fixed in focal), then this can be re-evaluated.
