Re: IPA Compat + ID Views + AIX 7.1
by wouter.hummelink＠kpn.com
Hi All,
We have our basic configuration working now however AD trusted users cannot log in. The system reports:
Can't retrieve attribute SYSTEM for NOUSER: No such file or directory
In LDAP Access logs we see AIX query user@<ad.domain<mailto:user@%3cad.domain>> and directly after <user> on slapd.
The same behavior happens with SU and that results in a session with empty HOME and SHELL variables (and an error report that you can't change directory to '')
LSUSER command do however return correct information about these users. (IPA groups included)

Thank you for pointing that out.
I should of course have been more specific: native aix sudo does not support ldap and therefore sudorules from ldap, but it is possible
to install a different sudo version with ldap enabled.
Unfortunately, in our case, using external rpm's is not an option.

As far as I found out, it is not possible to integrate sudo rules from IPA into AIX. sudo on aix does not support that.
You will have to maintain /etc/sudoers by som other means.
Thats where you are mistaken. It is possible to integrate sudo rules into AIX, I've done it and have documented it here: https://www.freeipa.org/page/SUDO_Integration_for_AIX
Give it a try, its a fairly simple procedure.
P.S.
IBM has recently pimped the AIX toolbox RPMs and even implemented it as a YUM server. I haven't tried using these new RPMs yet to see if they work with sudo integration.
If you want to keep it safe, user perzl RPMs as I describe on the documentation. If you want, and I would appreciate it if you would, give the new RPMs from toolbox a go and if it works please update the documentaion, or send me your notes and I'll update it.
Atenciosamente/Best Regards

Also remember: user can be locked in AIX so use smitty to unlock user and reset login attempts.
As far as I found out, it is not possible to integrate sudo rules from IPA into AIX. sudo on aix does not support that.
You will have to maintain /etc/sudoers by som other means.
Hope that helps, good luck.

Yes, kinit works with IPA users. GSSAPI authentication is not keeping it simple, since we want passwords to work before trying TGS based logins over GSSAPI.
The keytab works sinds lsuser is still able to get user data. (Documentation specifies that enabling krb5 in ldap.cfg makes the bind user and password moot, secldapclntd uses krb5 to identify itself to IPA)
Also we are able to kinit host/aixlpar.example.org(a)EXAMPLE.ORG<mailto:host/aixlpar.example.org@EXAMPLE.ORG> -kt /etc/krb5/krb5.keytab
We van try using su from an unprivileged user, but su has some different issues altogether, it doesn't like @ in usernames which we need at the next stage (integrating AD Trust)

The shell is shown correctly as ksh in lsuser, so that doesnt appear to be an issue for the ID view.
My advice would be to start simple ,prove that your authentication works and you can develop a more elaborated setup afterwards. If you combine them all together it will be a trial and error which eventually will work at some point.
Do you have the correct keytabs in /etc/krb5/krb5.keytab ? can you run kinit (with password and with the keytab) from aix and get a ticket from Kerberos ? can you su to an IPA account ? do you have GSSAPIAuthentication enabled in sshd_config ?
From what you've described i would suspect that your keytab is not correct , but that should be confirmed only by answering the questions above.

Onderwerp: Re: [Freeipa-users] IPA Compat + ID Views + AIX 7.1
Hello Wouter.
It may seem silly, but try installing bash on one AIX server and test authenticating against that one.
Its a single rpm with no dependencies. For me it did the trick and I ended up doing that on all my AIX servers.
Let me know how it goes or if you have any issues.
Best Regards

Hi All,
We're running a POC to integrate IPA and AIX using AIX KRB5LDAP compound module.
All the moving parts seem to be working on their own, however logging in doesn't work with SSH on AIX reporting Failed password for user <xxx>
We're using ID views to overwrite the user shell and home dirs. (Since AIX will refuse a login with a nonexisting shell (like bash))
AIXs lsuser command is able to find all of the users it's supposed to and su to IPA users works.
Also when a user tries to log in I can see a successful Kerberos conversation to our IPA server.
Tips for troubleshooting would be much appreciated, increasing SSH log level did not produce any meaningful logging.

Re: help - trying to get Solaris IPA client to use AD credentials
by wouter.hummelink＠kpn.com
To use IPA with trusts you need to use the compat tree. See https://www.freeipa.org/page/V4/Migrating_existing_environments_to_Trust
If you happen to get it working please share your experiences. Solaris is one of my future targets.

My AD credentials work fine on Linux (sssd) IPA clients but I'm not familiar with configuring an openldap client to use AD credentials. Currently the Solaris client can only see IPA users.

Re: CA CRL not tracking any certificates. Normal?
by Christophe TREFOIS
Update.
Thanks to the invaluable help of Florence. Truly terrific.
What we ended up doing.
Investigate why it happened. No idea.
Check that certificates on the other CA are still valid. Check
Move CRL to the working CA. Check
https://access.redhat.com/documentation/en-US/Red_Hat_Enterprise_Linux/7/...
Figure out the parameters to pass to getcert to start-tracking the 8 certificates. Check
Execute the following commands to start tracking the certificates.
getcert start-tracking -d /etc/httpd/alias -n "Server-Cert" -c IPA -p /etc/httpd/alias/pwdfile.txt -C '/usr/libexec/ipa/certmonger/restart_httpd'
getcert start-tracking -d /etc/dirsrv/slapd-UNI-LU -n "Server-Cert" -c IPA -p /etc/dirsrv/slapd-UNI-LU/pwdfile.txt -C '/usr/libexec/ipa/certmonger/restart_dirsrv UNI-LU’
Figure out Pin for hidden Pin entry
grep internal /etc/pki/pki-tomcat/password.conf
Run the commands by pvodiing pin on CLI
getcert start-tracking -d /etc/pki/pki-tomcat/alias -n "Server-Cert cert-pki-ca" -c dogtag-ipa-renew-agent -P <pin code> -B '/usr/libexec/ipa/certmonger/stop_pkicad' -C '/usr/libexec/ipa/certmonger/renew_ca_cert "Server-Cert cert-pki-ca”'
Realize a helper command was missing. Add it.
getcert add-ca -c dogtag-ipa-ca-renew-agent -e /usr/libexec/certmonger/dogtag-ipa-ca-renew-agent-submit
Add the remaining certificates
getcert start-tracking -d /etc/httpd/alias -n "ipaCert" -c dogtag-ipa-ca-renew-agent -p /etc/httpd/alias/pwdfile.txt -B '/usr/libexec/ipa/certmonger/renew_ra_cert_pre' -C '/usr/libexec/ipa/certmonger/renew_ra_cert'
getcert start-tracking -d /etc/pki/pki-tomcat/alias -n "caSigningCert cert-pki-ca" -c dogtag-ipa-ca-renew-agent -P <pin code> -B '/usr/libexec/ipa/certmonger/stop_pkicad' -C '/usr/libexec/ipa/certmonger/renew_ca_cert "caSigningCert cert-pki-ca"'
getcert start-tracking -d /etc/pki/pki-tomcat/alias -n "subsystemCert cert-pki-ca" -c dogtag-ipa-ca-renew-agent -P <pin code> -B '/usr/libexec/ipa/certmonger/stop_pkicad' -C '/usr/libexec/ipa/certmonger/renew_ca_cert "subsystemCert cert-pki-ca"'
getcert start-tracking -d /etc/pki/pki-tomcat/alias -n "ocspSigningCert cert-pki-ca" -c dogtag-ipa-ca-renew-agent -P <pin code> -B '/usr/libexec/ipa/certmonger/stop_pkicad' -C '/usr/libexec/ipa/certmonger/renew_ca_cert "ocspSigningCert cert-pki-ca"'
getcert start-tracking -d /etc/pki/pki-tomcat/alias -n "auditSigningCert cert-pki-ca" -c dogtag-ipa-ca-renew-agent -P <pin code> -B '/usr/libexec/ipa/certmonger/stop_pkicad' -C '/usr/libexec/ipa/certmonger/renew_ca_cert "auditSigningCert cert-pki-ca"'
Check that the certificates match the other CA.
getcert list
Check that all are Monitoring.
[root@toto2 ~]# getcert list | grep MONITORING | wc -l
8
Check that Serials match between the two CA servers.
certutil -L -d /etc/httpd/alias -n ipaCert | grep Serial
certutil -L -d /etc/pki/pki-tomcat/alias -n "auditSigningCert cert-pki-ca" | grep Serial
certutil -L -d /etc/pki/pki-tomcat/alias -n "caSigningCert cert-pki-ca" | grep Serial
certutil -L -d /etc/pki/pki-tomcat/alias -n "subsystemCert cert-pki-ca" | grep Serial
certutil -L -d /etc/pki/pki-tomcat/alias -n "ocspSigningCert cert-pki-ca" | grep Serial
certutil -L -d /etc/pki/pki-tomcat/alias -n "auditSigningCert cert-pki-ca" | grep Serial
The other 3 are supposed to be different.
After that, we move the CRL back to the original server, and assume everything is Ok.
If anybody has any comments on this process, please do let the community know as I hope im not the only one with this problem.
Kind regards,
Christophe
