[Freeipa-users] Extending IPA schema for Federation services.

[Steven Jones]

Hi,

Is it sensible/better to extend the scheme before I start adding users? or doesnt it matter?  From my perspective extending a system in use carries risk and impact to users, so its seems safer to extend it before I have any users, even if its un-used for now/?

Apart from that I dont know....for now I would live with the extended schema for the user....populating the fields would be something I would look at when its decided what we will be doing....no one yet knows or at least have not told me what they will be doing.

I suspect in the end we will draw the contents from AD with winsync?  

or populate/inject it directly via our Oracle identity system......so I'm not sure we will need the ui / gui....I dont expect to add content via it, I suspect I might need to fault find to make sure the data is there but I assume ldap search tools will return this anyway?

However for other sites they may well not have an AD or user provisioning system.......

So I think the schema has to be done/extended for IPA to be viable in tertiary institutions in NZ, without it not many if anyone will use IPA they will stay with openldap.  So each person should have these I think.....they may not be used initially but once extended initially then I dont have to extend the schema later.

The Idp allows remote tertiary organisations to query us and say our user is we legit....they then use their LDAP to provide resources via the SdP.  So the Idp provides an identity to remote ppl and the SdP provides access to a resource at our end. later I expect we will have to to the SdP bit got our high performance cluster and storage...

The question is simple: how you plan to manage these attributes in IPA?
Do you expect them to be a part of the UI/CLI or they should be hidden
there and be managed via ldapmodify and other data sync tools?

This make the whole difference especially the UI part. Depending upon
these expectations the scope would be different.
