I'm currently trying to mix local and LDAP users on an AIX 7.1.
I've triied many things.
My LDAP Server in on a CentOS - OpenLDAP (which works fine with linux).
I'm currently stuck on AIX at how to declare LDAP AND Local users.
Here's what i did :
I also triied
But like this, i can't connect on my local users but i can connect to LDAP user with ssh and while connected to my AIX.
With the current configuration, i'm able to login to local and LDAP users BUT while trying throught ssh, i get "Permission denied, please try again." error

afaiu users are there, both local and LDAP, you can login using both types of users using standard AIX tools/procedures, such as "normal" login, telnet, ftp, but you receive some error trying to open ssh session. Am I right?
Do you have problems opening an SSH session with an LDAP user or with a local AIX user or with both types of users?

In fact i would like AIX users works like Linux users (at least it works like this on my Linux servers)

When you change the default-Stanza to LDAP
you have to specify for all local (already existing) users SYSTEM = "files" and registry = files - or e.g. the login process will search them on the LDAP-Server.
If LDAP is the default you need to specify that a user should create or exists locally:

Ok, first things first.
a) for ease - become root/su and verify with id
b) make sure root is local, i.e., not LDAP administered (system and registry settings)
c) check your current defaults for SYSTEM and registry
d) notice in the comments the example for SYSTEM way back when (1995ish) when DCE was more popular. I will rephrase this:
In other words, "compat" is only used when DCE is unavailable. Yours should substitute DCE with LDAP.
e) From memory (i.e., without additional testing) I cannot say exactly what registry = LDAP is doing. But I expect, not what you expect. Maybe if you have added the AIX schema into your CentOS LDAP server it might work. But since mkuser/chuser/etc -R LDAP is not working I expect the LDAP server is refusing because it does not have the AIX (LDIF) schema for all the attributes in /etc/security/user (to name just one of the registry 'files').
I suggest returning "registry = files" as the default setting.
f) For users, rather account names, that must be local add at least "SYSTEM=compat" to the user, e.g., for michael
Other stuff) - back from 2000 when I designed the AIX security curriculum.
The key two attributes for Identification (aka username) and Authentication (aka password verification) are auth1 and SYSTEM. This is easy to delegate to an external I&A service, e.g., LDAP, DCE or kerberos server.
The third /etc/security/user attribute is registry - and, with no access to program code, design documents, etc. to verify it I have always understood this to be where to look for additional information about a user that is not uid/gid to username/groupnamelookup (and v.v.). In a literal sense I take this to mean - when registry=LDAP (as is your case) to not even look in /etc/passwd for my HOME directory or default shell (for the RFC2307 attributes that any UNIX oriented LDAP server should have).
You might be able to test this by changing the home directory of a user using both -R files and -R LDAP. If you do, please post results and expand my understanding!

Thanks for your reply,
I've already triied this, it's not a suitable solution as we may create local and LDAP users anytime. What could be perfect is something like :
I really want to stay with the default behavior:
all user operations will be local and if they can't be performed locally, they will try the LDAP.
Example ---------- Post updated at 07:13 AM ---------- Previous update was at 07:01 AM ----------
Thanks for your reply,
a) b) I'm root
c) My defaults
e) registry = LDAP
This does not really do what i want as when you mkuser a new user, his registry will be on LDAP by default, and i want it to be files by default.
f) For users, rather account names, that must be local add at least "SYSTEM=compat" to the user, e.g., for michael
It's not something that i would like to as as we have a large number of accounts and they are not all the same depending on the server. It would be a big work to declare the registry and SYSTEM parameters of our local users.
Other stuff) I understood that registry is where to look for user informations and security files.
If you declare registry to LDAP, AIX will look for the user's files (passwd, group, shadow) on the LDAP, even if the user has SYSTEM = compat.
Here's an example:
Conditions : SYSTEM = compat, registry = LDAP
Now the same user test with registry = files ---------- Post updated at 07:34 AM ---------- Previous update was at 07:13 AM ----------
I'm trying to exactly do what i said earlier
If i put registry to LDAP, all user will be searched on the LDAP.
I think i need the SYSTEM = 'compat or LDAP' to login to local and LDAP users.

Normally, for user authentication admins want only one or the other, not both being checked.
I have never tried SYSTEM = compat OR compat[UNAVAIL] AND LDAP as I expect compat to always be available. Assuming compat[UNAVAIL] does not work then I think SYSTEM = compat OR LDAP comes closest to your authentication needs.
For accounts that must be local, like root - the solution has been to add specific
entries.
If your goal is to be as close to default as possible, set registry=files

Hi,
I have been asked to create a ksh script that will search against an LDAP directory from various HP-UX, SUSE, and AIX 5.3 and 6.1 machines.

Hi Gurus,
I have a script that requires me to switch from local user to root. Anyone who has an idea on this since when i switch user to root it requires me to input root password.
