Hello,
I'm currently trying to get users' home directories automounted, with
maps stored in LDAP. I found that I want some things which the current
lookup_ldap module cannot do (I believe), so I decided to patch it :-)
Doing this, I discovered the undocumented(?) yet (IMO) useful option
--no-slashify, which however seems to be buggy in 4.1.3, so I suggest
a tiny fix to actually make it work:
diff -u -r autofs-4.1.3-orig/modules/parse_sun.c autofs-4.1.3/modules/parse_sun.c
--- autofs-4.1.3-orig/modules/parse_sun.c 2004-05-18 14:22:40.000000000 +0200
+++ autofs-4.1.3/modules/parse_sun.c 2004-09-22 15:36:56.539912580 +0200

}
- if (strmcmp(xopt, "slashify-colons", 1))
+ if (!strmcmp(xopt, "slashify-colons", 1))
ctxt->slashify_colons = bval;
else
error(MODPREFIX "unknown option: %s",
My actual patch of lookup_ldap.c grew somewhat larger than initially
planned (so I'm not posting a diff), and I believe it could be useful
and could be merged into the autofs source (after more testing, of
course), so I put a modified lookup_ldap.c at
http://www.timof.qipc.org/autofs-4.1.3-patch/lookup_ldap.c-patched
I invite everyone using autofs with LDAP to try and use it. Basically,
it will parse map names in (almost) the form of LDAP URIs as defined
in rfc2255:
[[scheme:]//server[:port]][/basedn][?attr[?scope[?filter[?ext]]]]]
This gives more flexibility: e.g., you can get TLS, you can use your
own LDAP schema, and apply arbitrary filters; details are in
http://www.timof.qipc.org/autofs-4.1.3-patch/README.ldap-patch
The last example there is approximately what I wanted to have, and
what I am currently (test-)using (and so far it seems to work well):
In addition to being able to connect with TLS, I wanted to put the
automountInformation for home directories right into the account
database (rather than into a separate subtree), using homeDirectory
(which is there anyway) as the "key" (ie, mountpoint) attribute.
I tried to keep everything backward compatible: the current form of
ldap map names, [//host/]base, should still work, with both
autofs.schema and nis.schema, so not too many things should break.
(and following Jun Futagawa's recent suggestion, the modified lookup
module will print human-readable LDAP error messages, where possible.)
Regards,
Timo
