Hi, thank you.
ldapsearch reply: search: 2 result: 32 No such object matchedDN: CN=RpcServices,CN=System,DC=rwe,DC=tt text: 0000208D: NameErr: DSID-03100238, problem 2001 (NO_OBJECT), data 0, best match of: 'CN=RpcServices,CN=System,DC=rwe,DC=tt' actually when I look under the CN=RpcServices,CN=System,DC=rwe,DC=tt - it is empty. Do I missed to set something on the AD site ?

In the /usr/lib/python2.7/site-packages/ipalib/plugins/trust.py: It's working with msSFU30MaxUidNumber and msSFU30OrderNumber. If I understand it right, it is base uid number and the number of uids in range. If not discovered nor given via CLI, then it generate random base and add some default_range_size. So these two attributes must be set to use ipa-ad-trust-posix range ? Could anybody help me how and where to check these attributes ? I have looked in the ldapsearch dump from my AD(Global calaog) and I can see these attributes only in schema - so no values assigned. I'm using W2012 R2.

You can check the exact steps and attributes searched by looking at the add_range function definition in /usr/lib/python2.7/site-packages/ipalib/plugins/trust.py I would suggest reviewing the output of 'ipa idrange-find' to confirm that the range matches up with the uid and gidNumbers of your AD environment.

Please can anybody provide some simple reference settings of IPA-AD trust where users are able to get uid from AD - not from IPA ID pool ? I have tried to set values of attributes before and after creating trust, I have tried different sssd setting but I'm still getting uid from IPA idrange pool instead of from AD user's attribute. What exactly is IPA checking when it tries to decide what type of trust will be set - ['ipa-ad-trust-posix', 'ipa-ad-trust'] ? Do I have to mandatory fill some AD user's attributes to get it work ? Currently I'am testing just with uidNumber and gidNumber. There is almost no documentation about this topic so I don't know what else I can try ...

I think idviews are better for overriding POSIX attributes for a specific set of hosts, but in your environment, it sounds like you want to use the POSIX attributes across the board. > > So my questions are: > > Is it possible to read user's POSIX attributes directly from AD - namely uid > ? Yes > Which atributes can be stored in AD ? Homedir is a bit special, for backwards compatibility the subdomains_homedir takes precedence. The others should be read from AD. I don't have the environment set at the moment, though, so I'm operating purely from memory. > Am I doing something wrong ? > > my sssd.conf: > [domain/a.example.tt] > debug_level = 5 > cache_credentials = True > krb5_store_password_if_offline = True > ipa_domain = a.example.tt > id_provider = ipa > auth_provider = ipa > access_provider = ipa > ipa_hostname = ipa1.a.example.tt > chpass_provider = ipa > ipa_server = ipa1.a.example.tt > ipa_server_mode = True > ldap_tls_cacert = /etc/ipa/ca.crt > #ldap_id_mapping = true > #subdomain_inherit = ldap_user_principal > #ldap_user_principal = nosuchattribute > > [sssd] > services = nss, sudo, pam, ssh > config_file_version = 2 > > domains = a.example.tt > [nss] > debug_level = 5 > homedir_substring = /home > enum_cache_timeout = 2 > entry_negative_timeout = 2 > > > [pam] > debug_level = 5 > [sudo] > > [autofs] > > [ssh] > debug_level = 4 > [pac] > > debug_level = 4 > [ifp] > > Thanks, > Jan BQ_END
