Sorry for bursting into your conversation and bringing up an old
issue again, but it seems to be quite related to this discussion:

A while ago I did suggest a generalized syntax for LDAP map names,
by implementing an already existing standard: LDAP URLs as in rfc2255.
This would be more a "meta"-standard, as it does not enforce any
specific schema, but allow one to use arbitrary schemas, encoded
into the map name. So far, I used to think in terms of schemas with
just two relevant attributes (automount key and information), but I
actually start to like the idea of splitting automountInformation
into several attributes.

The current map name format would be subset of the URL syntax, so
compatibility could be preserved.

I submitted a patch for autofs4 (http://timof.qipc.org/autofs), which
however didn't make it into autofs5. I understand that this would be
an ambitious change, and bringing other parts of autofs up to standard
was probably more urgent; however, it could give plenty of room for
future improvements (like the evolution of a new standard schema), while
staying compatible with traditional schemas (at least, I don't see any
fundamental issues here), so I would still like to hear your opinions
about implementing this in a future version?

...btw:

If I understand this correctly (I'm not familiar with AFS), this is pretty
much the reason why I started to patch lookup_ldap.c in the first place:
to pull automount information from user account entries (rather than from
an independent hierarchy), with the "uid" attribute used as the autmountKey,
when mounting user directories. Seems the natural way of doing it to me.
