[Freeipa-users] FreeIPA for Linux desktop deployment

[nasir nasir]

Adam/Nalin,
Two cases,
  1) When I am testing this by manually mounting the nfs share(which is /xtra )on the NFS server itself using the following command,
 #mount -vvvv -t nfs4 -o sec=krb5 nfsserver.cohort.org:/ /home
I get whatever problem I described in previous mail(permission issues). Now this could be because here IPA is not managing the user/group permissions completely(Correct me if I am wrong in this assumption) and all the problem you described happen.
2) When I DO NOT mount manually and instead I try to login as a new user on the nfsserver machine,  It creates the home folder for this user on the /home partition of nfsserver machine because automount is NOT working and hence there is no mounted partition to confuse things. So to be able to test it properly, I need to fix the issue in automount and get the case #2 tested and working properly with /home automatically mounted from the nfsserver. This is my "ipa automountlocation-tofiles default"  output,
/etc/auto.master:/-      /etc/auto.direct/share  /etc/auto.share/home   /etc/auto.home---------------------------/etc/auto.direct:---------------------------/etc/auto.share:---------------------------/etc/auto.home:*       -rw,sec=krb5,soft,rsize=8192,wsize=8192 nfsserver.cohort.org:/xtra/home/&

Is this OK ? Please help.
Thanks and regards,Nidal

              Adam,
              

              
              Thanks indeed!
              

              
              I tried your suggestions. 
              

              
                -- I can mkdir
                -- When I try to chown, I get the following error
              

              
              
                chown: changing ownership of `nasir': Operation
                    not permitted
              
              

              
              Could you please explain me what do you mean by 'You
                probably need rwx permissions in /etc/export' ? This is
                my /etc/export file,
            
          
        
      
    
    

    see the  '(rw'  in those lines?  That indicates read and write
    privs, but not execute.  

    

    I'm not an nfs guru, so I might be wrong.  this post suggests that I
    am wrong:

    SInce IPA is managing the IDs, they should be in sync across the NFS
    and autmounted client machines, but there might be something not
    right in the setup.  if the IPA server isn't managing the machine
    that serves as your NFS server, then the IDs are certainly going to
    be out of sync.

    

    

    

    
      
        
          
            
              

              
              
                /xtra
                     *(rw,fsid=0,insecure,no_root_squash,no_subtree_check)
                /xtra
                     gss/krb5(rw,fsid=0,insecure,no_root_squash,no_subtree_check)
                /xtra
                     gss/krb5i(rw,fsid=0,insecure,no_root_squash,no_subtree_check)
                /xtra
                     gss/krb5p(rw,fsid=0,insecure,no_root_squash,no_subtree_check)
              
              

              
              
              Also, I have configured a separate client machine
                (RHEL 6.1) and configured it as NFS server (previously
                my NFS server was IPA server itself) and the result is
                same. All the above commands are from this client
                machine only.
              

              
              Thanks indeed again!
              

              
              Regards,
              Nidal
              

              
              

              
              

              
              

              
              
                
                  
                    
                      
                        
                          
                            
                              

                                 
                              
                                oddjob-mkhomedir[16401]: error
                                    setting permissions on /home/abc:
                                    Operation not permitted
                              
                            
                          
                        
                      
                    
                    

                    It might be a root squash issue.  My guess is that
                    the order of operations for creating a root
                    directory, which is done by root, is:

                    

                    1.  mkdir /home/userid

                    2.  chown uid:gid  /home/userid

                    

                    It sounds from the error message that the first
                    stage happened, but NFS is not allowing the second
                    stage.  To confirm,  as a root (and kinit admin)
                    user on the client machine, just try these two steps
                    in order and see if they still fail.

                    

                    chown is a different system call from mkdir, and
                    might have different nfs enforced permissions.  You
                    probably need rwx permissions in /etc/export.
