Thank you Lukas and Jakub, Lukas: sorry for the typo, my sssd.config reflect the correct parameter name. i'll test the min and max range then post the results. Jakub: all of a sudden it started working yesterday and i was able to enumerate the groups now and yes i have configured two forests in sssd.conf. this is a very large deployment so i hope i can share the results here so it can benefits anyone want to implement in large AD environment. you guys did a wonderful job Thanks for that. if there are any pitfalls i should be aware of please do let me know though to take into considerations Thanks.

another question: how are you doing with ID collisions in cross realms scenarios? currently both forest configured with ldap_idmapping_range_size = 20000000 anything less than this sssd will complain its not able to convert SID to unix ID and login fail. i didn't configure _range_max parameter, is there any recommendations for setting this across the two domains? Thanks From: [email protected] To: [email protected] Subject: RE: sssd and external trust Date: Wed, 12 Nov 2014 17:18:00 -0800 it's getting interesting, I setup the production lab and was able to authenticate against the new forest DC fine but getent group NEWFOREST\\GROUPNAME return 0 results i compiled latest SSSD on RHEL 6.6 the error i see in the log exactly match this https://bugzilla.redhat.com/show_bug.cgi?id=1002592 when i resolve group in the first forest it works fine, when i try the new forest it return 0 results and thing my provider is offline although it is not! any pointer is appreciated Thanks From: [email protected] To: [email protected] Subject: sssd and external trust Date: Wed, 12 Nov 2014 14:26:21 -0800 Hi Team, i have a very complex/large AD setup which SSSD successfully integrated the Linux machine onto it. now after acquiring another company we have to integrate a separate AD forest which is now trusted by our forest root. I understand that SSSD won't work with external trusts and only support the same forest. what is the best practice to allow authentication from the new trusted forest. on my test lab I added the new forest to a new domain section, then used adcli to create a computer account on the new forest. so technically this Linux machine is now joined to two domains klist -k show correct entries for both forests nothing i changed in krb5.conf my tests are positive and i was able to login both forests from my Linux machine. is this supported scenario and what is the best practice when having external trust?. any detailed guidance will be highly appreciated (no documentation about this except for IPA which we don't use) Thanks
