I can and use IPA users on an AIX client. As well as groups. But

group membership does not seem to be configured correctly...

Anyone has a hint what could be misconfigured?
There isn't enough information. How is LDAP configured, what
search bases?
What is ipa-aix-g? What membership do you expect?
How does the group relate to the user you id'd?
I'll try to clarify.
ipa-aix-g is the IPA group containing several members as y179768
for example.
/etc/security/ldap/ldap.cfg:
userbasedn:cn=users,cn=accounts,dc=linux,dc=mydomain,dc=at
groupbasedn:cn=groups,cn=accounts,dc=linux,dc=mydomain,dc=at
Which LDAP schema AIX configuration is expecting to use? RFC2307 or
RFC2307bis?
The primary LDAP tree in FreeIPA is using RFC2307bis (e.g.
member/memberof, not memberuid attributes).
I did not do the AIX client configuration by myself. I am just trying
to assist my AIX colleagues to find the problem...
What I saw were two map files in /etc/security/ldap named
2307user.map and 2307group.map. So I am suspecting that they are
trying to use RFC2307. In order to use that we would need to use a
different configuration? Is this where the compat tree comes into
place?
Correct. If your clients are using RFC2307, compat tree is what
could be
used to provide them the data in the format they expect. However, I'd
rather ask AIX admins to use RFC2307bis. For example,
https://www.ibm.com/support/pages/aix-how-configure-aix-ldap-or-krb5ldap-client
talks about other maps for AD (which is also using member/memberof,
not
memberuid).
Just to avoid any confusion. Is the link you provided an example for
2307bis configuration? I am asking because the term "2307bis" is not
mentioned at all in the article...
It isn't and the group configuration is rather subtle.
Near as I can tell you want to look for:
#users SEC_LIST memberUid m na yes
users SEC_LIST member m na yes
memberUid is RFC 2307 and member is RFC 2307bis.
I tried to configure an AIX client the bis way. Now the IPA group
shows its members. Perfect. However, the id command does not list the
IPA group. As a result, sudo commands do not work because these rights
were given to the IPA group.
I've added
groups SEC_LIST memberof s
na yes
to the 2307bisuser.map file because I thought that might fit. But
unfortunately it did not.
What might I be missing?
Forgot to mention that lsuser -R LDAP someuser also does not reveal the
IPA group.

Andrey Klyachkin from IBM answered my question on LinkedIn:
Ronald, did you check LDAP client mappings on AIX? By default if you
followed the article AIX will search for memberUid attribute in
cn=groups. It is RFC2307, not RFC2307bis. You can update
/etc/security/ldap/2307group.map (or create your own map) and define
member attribute instead of memberUid. After restart secldapclntd should
find the secondary groups.
Another possible confusion place - AIX expects usernames in member or
memberUid attribute. If your LDAP administrator wrote user's full CN in
the attribute instead of just username, AIX will not identify it as a
secondary group for the user. As far as I could test IPA doesn't allow
to write just usernames into the attribute and wants to have full CNs.

Could this be the issue?
