integrating custom NIS maps into LDAP

[Kevin Collins]

Hi,

does anyone have any experience with migrating NIS to LDAP where custom NIS
maps are in use? I am working on a project to migrate to LDAP from NIS and we
currently have 3 custom NIS maps I have implemented and we rely on heavily for
automation.

Do I need to define my own schema for this, or is there some simpler method
available?

Thanks for any advice, examples, web-sites, etc that you can provide.

Kevin

RFC 2307 is the definitive reference on supporting NIS-style data on
LDAP. If you consult that RFC, you'll see that there is support for
an 'nisMap' object class, which can be used to represent any arbitrary
key/value mapping.

The trick isn't getting that data into LDAP, the trick is rewriting
whatever software you have that currently consults your custom NIS
maps so that it uses your unique nisMap entries in your LDAP.

Can you speak a bit about what it is that you are wanting to do?

Ok - I'll take a deeper look at the RFC...

This is not a problem, it is all ksh and/or Perl parsing the output, so
changing will be pretty strat forward.

We are a large, highly automated SAP shop and (as one example) use a custom map
to track information relative to a specific SID: system number, SAP usage (R/3,
BW, etc), type (prod/stage/devl), default client, Oracle home dir, etc.

Currently this is a colon-delimited list, so I can probably just use the nisMap
you've already mentioned, but I was thinking it might be nice to have "named"
elements (such as "sysNumber", "sapUsage", "supType", "defaultClient", etc),
which would simplify the work our scripts are doing in parsing the list.
