Full Discussion: Mix LDAP and LOCAL user on AIX
Operating Systems AIX Mix LDAP and LOCAL user on AIX Post 302961208 by MichaelFelt on Wednesday 25th of November 2015 08:17:36 AM

Maybe I do not understand the question. But, let's say michael exists in both LDAP and AIX domains.

To change the account michael 'locally' I would use:

# chuser -R files .... michael

And the same, or a different change on LDAP would be:

# chuser -R LDAP .... michael

However, I expect most changes using chuser -R LDAP ... michael will fail if your server only supports the RFC2307 DIT or LDIF specification (basically, what is found in /etc/passwd and /etc/group and the shadowed encryption of the password).

Basics:
when you ran the mksecldap command you configured the file /etc/security/ldap.cfg and arranged for the daemons to start.

Look at this section on your server - I do not have LDAP configured so all are commented out - you should have a few uncommented.

Line numbers are approximate!
unix_auth is default, and preferred
Code:
   +30  # Authentication type. Valid values are unix_auth and ldap_auth.
   +31  # Default is unix_auth.
   +32  # unix_auth - Retrieve user password and authenticate user locally.
   +33  # ldap_auth - Bind to LDAP server to authenticate user remotely through LDAP.
   +34  #authtype:unix_auth

Preferred is "system" and update /etc/security/login.cfg to use sssh256
Code:
   +60  # Default is "crypt".
   +61  #  crypt      - Specifies the legacy crypt() (DES) algorithm.
   +62  #  system     - Specifies the syste-wide password algorithm that is
   +63  #               defined in /etc/security/login.cfg. Using syste-wide
   +64  #               password algorithm may require that LDAP server's
   +65  #               password encryption be disabled to avoid double
   +66  #               encryption, which can make the password unusable.
   +67  #pwdalgorithm:crypt

These are the user attributes defining the schema used. Are these uncommented? What do they point too?

Code:
   +69  # AIX-LDAP attribute map path.
   +70  #userattrmappath:/etc/security/ldap/aixuser.map
   +71  #groupattrmappath:/etc/security/ldap/aixgroup.map
   +72  #idattrmappath:/etc/security/ldap/aixid.map

Code:
michael@x071:[/etc/security/ldap]ls /etc/security/ldap/*.map
/etc/security/ldap/2307aixgroup.map  /etc/security/ldap/aixuser.map        /etc/security/ldap/sfu30user.map
/etc/security/ldap/2307aixuser.map   /etc/security/ldap/sfu20group.map     /etc/security/ldap/sfur2aixgroup.map
/etc/security/ldap/2307group.map     /etc/security/ldap/sfu20user.map      /etc/security/ldap/sfur2aixuser.map
/etc/security/ldap/2307user.map      /etc/security/ldap/sfu30aixgroup.map  /etc/security/ldap/sfur2group.map
/etc/security/ldap/aixgroup.map      /etc/security/ldap/sfu30aixuser.map   /etc/security/ldap/sfur2user.map
/etc/security/ldap/aixid.map         /etc/security/ldap/sfu30group.map

And finally, for the basics: what is active/inactive here?

Code:
   +74  # Base DN where the user and group data are stored in the LDAP server.
   +75  # e.g., if user foo's DN is: uid=foo,ou=people,cn=aixdata
   +76  # then the user base DN is: ou=people,cn=aixdata
   +77  #userbasedn:ou=people,cn=aixdata
   +78  #groupbasedn:ou=groups,cn=aixdata
   +79  #idbasedn:cn=aixid,ou=system,cn=aixdata
   +80  #hostbasedn:ou=hosts,cn=aixdata
   +81  #servicebasedn:ou=services,cn=aixdata
   +82  #protocolbasedn:ou=protocols,cn=aixdata
   +83  #networkbasedn:ou=networks,cn=aixdata
   +84  #netgroupbasedn:ou=netgroup,cn=aixdata
   +85  #rpcbasedn:ou=rpc,cn=aixdata
   +86  #automountbasedn:ou=automount,cn=aixdata
   +87  #aliasbasedn:ou=aliases,cn=aixdata
   +88  #bootparambasedn:ou=ethers,cn=aixdata
   +89  #etherbasedn:ou=ethers,cn=aixdata
   +90  #authbasedn:ou=authorizations,cn=aixdata
   +91  #rolebasedn:ou=roles,cn=aixdata
   +92  #privcmdbasedn:ou=privcmds,cn=aixdata
   +93  #privdevbasedn:ou=privdevs,cn=aixdata
   +94  #privfilebasedn:ou=privfiles,cn=aixdata
   +95  #domainbasedn:ou=domains,cn=aixdata
   +96  #domobjbasedn:ou=domobjs,cn=aixdata

If it's not possible to do it on AIX well... I'll have to find a workaround.
I expect it is using, by default, the same schema (attribute mapping) in LDAP and it does in it's local files.

AIX includes an LDAP server at no additional charge for AIX user admin. Maybe using that will get you 90% of the way. You can still configure AIX to go to a 'foreign' LDAP server for "login" verification.
