Looking for suggestion on ID mapping.
I need to point to a ID provider over proxy
I have not found a concrete solution or some hint about how to setup
a
proxy to a ID provider and how sssd can point to that proxy for ID
mapping.
Can you rephrase your question? 'ID provider over proxy' should like
you
want some more details about SSSD's proxy provider as described in the sssd.conf man page. But this is unrelated to what I associate typically with 'ID mapping'. Please give a bit more details about what you are trying to achieve.
I am looking for a ID mapping solution. I do see following providers.
“proxy”: Support a legacy NSS provider. “local”: SSSD internal provider for local users (DEPRECATED). “files”: FILES provider. See sssd-files(5) for more
information
on how to mirror local users and groups into SSSD.
“ldap”: LDAP provider. See sssd-ldap(5) for more information
on
configuring LDAP.
“ipa”: FreeIPA and Red Hat Enterprise Identity Management
provider. See sssd-ipa(5) for more information on configuring FreeIPA.
“ad”: Active Directory provider. See sssd-ad(5) for more
information on configuring Active Directory.
I am looking for a suggestion. ad - won't work as we will not be provided Administrator
password
If the data for all users and groups is stored in AD this would be the most recommended provider. You do not need the Administrator password for SSSD to operate but a "normal" account which can read user and group data is sufficient. Typically this is machine account which is created when you join the Linux host to the AD domain.
I will check it out Monday at work. But I do remember trying to join with realmd and it was asking for Administrator password. I also tried with -U <mycuid> and it did not let me join.
I have to see if IT is willing to provide us a "machine account" to join our Linux servers
if that is a success that AD SID will automatically used to generate UID/GID, I think, correct?
Assuming AD can be used as auth and id provider, then I will need to find a solution to setup a proxy to AD, so all my 100+ servers do not need to setup with firewall and manage access. This last piece deserves a separate new email, so not looking for an answer for this.
Appreciate your help!
If you use realmd for joining the domain realmd will create a basic SSSD configuration automatically.
To join a domain you do not need the Administrator account either. Please check the AD documentation how to assign privileges to a "normal" account so that it can be use to join machines,
ldap - won't work as IT says not to use LDAP and use kerberos
instead for all things UNIX auth
You can use 'auth_provider = krb5' with 'id_provider = ldap'
and to use /etc/passwd for id (yikes, we have 100s of
servers to manage) files - I am not sure how to have a central files for all accounts local - seems deprecated proxy - I am not sure how to set that up, but seems like
easier
for a central ID provider?
It depends what your central ID provider is and if there already is an nss module for this provider. If your central ID provider is AD please see my comments there.
