Yes..

I agree though the message is confusing and we’ll be (most probably) looking at some autofs enhancements in the next sssd version..

As long as all the maps are returned, though, this is really only a
confusing error message. I think the code that causes it is in SSSD's
automounter client code, around line 172 with the current master:

172     if (len == 0) {
173         /* There are no more records. */
174         *_key = NULL;
175         *_value = NULL;
176         ret = ENOENT;
177         goto done;
178     } 

what you see in the output is just strerror(ENOENT)..
