Full Discussion: Mix LDAP and LOCAL user on AIX
Operating Systems AIX Mix LDAP and LOCAL user on AIX Post 302961210 by -=XrAy=- on Wednesday 25th of November 2015 08:18:26 AM

Okay,

i found a solution that seems to work (in my setup):

Security authentication mechanism in AIX

authcontroldomain attribute

AIX introduced a new alternative authentication control attribute "authcontroldomain" from AIX 6.1 Tl07 and 71 Tl01 releases. When this attribute is set, SYSTEM and registry attributes are stored or retrieved from that database. For local users, SYSTEM and registry attribute are stored in /etc/security/user file irrespective of the authcontroldomain value.

The authcontroldomain attribute needs to be defined with a loadmodule name which is defined in the /etc/methods.cfg or /usr/lib/security/methods.cfg file. This attribute needs to be defined in the /etc/security/login.cfg file under the usw stanza.

authcontroldomain attribute can be set for a system as using the chsec command. For example:

Code:
chsec -f /etc/security/login.cfg -s usw -a authcontroldomain=LDAP

Code:
/etc/security/user
default:
        SYSTEM = "files"
        registry = files

Quick Test: LDAP and local User Login works fine without further specifying SYSTEM or registry.


Regards

Security load modules are defined in /usr/lib/security/methods.cfg file. User identification is done based on order in, which load modules are defined in methods.cfg file. Local load module information is not defined in the /usr/lib/security/methods.cfg file. However, the user information will be verified first in local module; then the order that is defined in methods.cfg file will follow.

NAME

       pam_rhosts_auth - authentication management PAM module using ruserok()

SYNOPSIS

       /usr/lib/security/pam_rhosts_auth.so.1

DESCRIPTION

       The  rhosts   PAM  module,   /usr/lib/security/pam_rhosts_auth.so.1,  authenticates  a  user  via  the rlogin authentication protocol. Only
       pam_sm_authenticate() is implemented within this module. pam_sm_authenticate() uses the ruserok(3SOCKET) library function  to  authenticate
       the rlogin or rsh user. pam_sm_setcred() is a null function.

       /usr/lib/security/pam_rhosts_auth.so.1  is designed to be stacked on top of  the /usr/lib/security/pam_unix.so.1 module for both the rlogin
       and rsh services. This module is normally configured as sufficient so that subsequent  authentication  is  performed  only  on  failure	of
       pam_sm_authenticate(). The following option may be passed in to this service module:

       debug	       syslog(3C) debugging information at  LOG_DEBUG level.

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:

       +-----------------------------+-----------------------------+
       |      ATTRIBUTE TYPE	     |	    ATTRIBUTE VALUE	   |
       |MT Level		     |MT-Safe with exceptions	   |
       +-----------------------------+-----------------------------+

SEE ALSO

       pam(3PAM), pam_authenticate(3PAM), ruserok(3SOCKET), syslog(3C), libpam(3LIB), pam.conf(4), attributes(5)

NOTES

       The interfaces in  libpam() are MT-Safe only if each thread within the multi-threaded application uses its own  PAM handle.
