Hi, 
please can you help me with troubleshooting IPA clients in IPA - AD trust 
scenario ? We have two IPA servers and couple of clients running on RHEl 6 and 
7. IPA is running on RHEL 7.2. 
AD servers are in domains example.cz, cen.example.cz. Test users sits in 
cen.example.cz. IPA is subdomain of AD - vs.example.cz. 
Trust is set as one-way trust. User's POSIX attributes are stored in AD. 

ipa idrange-find 
---------------- 
3 ranges matched 
---------------- 
Range name: CEN.EXAMPLE.CZ 
First Posix ID of the range: 98800000 
Number of IDs in the range: 200000 
Domain SID of the trusted domain: S-1-5-21-527237240-1482476501-682003330 
Range type: Active Directory trust range with POSIX attributes 

Range name: EXAMPLE.CZ_id_range 
First Posix ID of the range: 68800000 
Number of IDs in the range: 200000 
Domain SID of the trusted domain: S-1-5-21-73586283-1958367476-682003330 
Range type: Active Directory trust range with POSIX attributes 

Range name: VS.EXAMPLE.CZ_id_range 
First Posix ID of the range: 930000000 
Number of IDs in the range: 200000 
First RID of the corresponding RID range: 1000 
First RID of the secondary RID range: 100000000 
Range type: local domain range 
---------------------------- 
Number of entries returned 3 
---------------------------- 

I have no problem to resolve AD users from both IPA server: 

IPA Server: 
root#:id tst99...@cen.example.cz 
uid=20019(tst99...@cen.example.cz) gid=5001(csunix) 
groups=5001(csunix),930000008(final_test_group) - this is correct 

but from IPA client: 
root#:id tst99...@cen.example.cz 
id: tst99...@cen.example.cz: no such user

All IPA clients have the same result - No such user. On the other hand kerberos 
works fine - I can do kinit with AD users both on IPA servers and clients. All 
IPA clients use the same DNS server as IPA servers. 


On IPA server, I can see that it is able to find test user in AD. Log is 
captured during IPA client request for id:

I can provide full log from IPA server, but its quite long. Could you point me 
what else I could try ? 

Thank you .
