--- Comment #3 from Ryan Tandy ryan@openldap.org --- Not mentioned here (or I guess in README) is that Ondřej made pw-argon2 configurable via parameters specified at load time.
https://git.openldap.org/openldap/openldap/-/commit/af5ed7c6e27d596dbed440c9...
e.g.
olcModuleLoad: pw-argon2 m=8192 t=5 p=3
m= Argon2 memory limit (in KiB if built against the reference impl, in bytes if built against libsodium)
t= iterations
p= parallelism (thread count for reference impl, ignored with libsodium)
Not a blocker for applying the patch, just making the note.
