ODBC/JDBC Auth on openSUSE running PAM/SSSD

Date: Monday, 15 May 2017, at 3:36 p.m.

Good day Informix gurus,

I am looking for help polishing off a configuration with our new IDS instance.

O/S: openSUSE Leap 42.1
IDS: 12.10.xC7

User authentication has been configured so that most users get authed against the AD.

I can't seem to figure out what needs to be done so that my configuration authenticates user logins successfully.

I am including the following file excerpts from the different configuration and log files related to this situation:

*** Excerpt from $INFORMIXDIR/etc/$ONCONFIG file:
DBSERVERALIASES dmart0prim,dmart0pam

*** Excerpt from $INFORMIXDIR/etc/sqlhosts file:
dmart0 onipcshm phoenix2.cantrexnw.local online_dmart0
g_dmart0 group - - e=dmart0sec
dmart0prim onsoctcp phoenix2.cantrexnw.local on_dmart0prim g=g_dmart0
dmart0sec onsoctcp DRPPhoenix on_dmart0sec g=g_dmart0
dmart0pam onsoctcp phoenix2.cantrexnw.local on_dmart0pam s=4,pam_serv=(informix),pamauth=(password)

*** Contents of the /etc/pam.d/informix file
auth sufficient
auth required debug
account sufficient
account sufficient debug
account required debug

Trying to connect to the database server using the SDK's Connect Test Demo interface, I get the following error displayed on the client side
ERROR [08004][Informix][Informix ODBC Driver][Informix] Server rejected the connection.

and the corresponding logged error(s) can be found in the following /var/log/messages excerpt

*** Excerpt from /var/log/messages
2017-05-15T15:00:04.644047-04:00 phoenix2 oninit: pam_sss(informix:auth): authentication failure; logname= uid=1001 euid=0 tty= ruser=entrepot rhost=cantrexbi.cantrexnw.local user=entrepot
2017-05-15T15:00:04.645713-04:00 phoenix2 oninit: pam_sss(informix:auth): received for user entrepot: 10 (User not known to the underlying authentication module)
2017-05-15T15:00:04.657913-04:00 phoenix2 oninit: pam_unix(informix:auth): authentication failure; logname= uid=1001 euid=0 tty= ruser=entrepot rhost=cantrexbi.cantrexnw.local user=entrepot

I believe that I have tried many combinations so far and I can't seem to determine why AD users are denied access when connecting through a client-server connection.

SSH connections work fine (even though they get authenticated through AD and SSSD but I can't seem to find the right settings to get the Informix PAM connections working.

Any help would be greatly appreciated.
