--- Comment #2 from Harald Schmalzbauer <bugzilla.freebsd at omnilan.de> ---
Sorry for the bad reproduction info.  The choosen values are nonsense and
inconsistent in the example...
But I guess that doesn't matter much.

Here's the breaking part:

Index: usr.sbin/mountd/mountd.c
===================================================================
--- usr.sbin/mountd/mountd.c    (Revision 349275)
+++ usr.sbin/mountd/mountd.c    (Arbeitskopie)

         */
-       names = namelist;
-       name = strsep_quote(&names, ":");
+       names = strsep_quote(&namelist, " \t\n");
+       name = strsep(&names, ":");
        /* Bug?  name could be NULL here */
        if (isdigit(*name) || *name == '-')
                pw = getpwuid(atoi(name));

This reverse-diff restores working state.
I have no idea what the intention was.
At least dlim seems to be unintentionally changed?

Thanks,

P.S.: Like mentioned, I consider this as severe surprise for useres updating to
11.3 and wondering why NFS doesn't work as before...
