Ldap sync differences between 13.x and 10.x?

we’re on 13.0.1 syncing a large ldap directory, and have seen some seemingly random 5xx’s returned when syncs run…still investigating before forming an opinion here, but noticed:


i’ve seen some ldap sync bugs fixed in changelogs which seemed specific to 14/15.x e.g.


but does that imply <= 15.0.1 so we should move to 15.0.2?

anyone had similar experiences?
