[Bug 1891548] Re: autofs-ldap's /etc/ldap/schema/autofs.schema crashes slapd

[msp3k]

I didn't realize that this was considered unusual.  AutoFs integration
has been a critical part of our infrastructure across multiple
departments at our university for decades, starting with NIS/NIS+.
 Without AutoFS integration we would be ... very, very sad.

I have filed a bug report w/ Debian and included a patch against Debian
Sid's autofs-5.1.6 source package: 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=968675

Since this is the same source file as Ubuntu 20.04 uses I've included
the patch file for your use, on the off chance that it would make
things easier (attached).

Looking at the up-stream source from 
https://mirrors.edge.kernel.org/pub/linux/daemons/autofs/v5/ it appears
that version 5.1.2's autofs.schema file was correct.  The typo first
appears in 5.1.3, released in May 24th 2017, and has affected every
release of autofs since.

I have also submitted a bug report, including a patch file, to the 
autofs at vger.kernel.org mailing list for the autofs developers.
