    Hi,

    I have AD server configured on windows 2012 server. I joined
    centos node to AD using sssd. I configured sssd with fully
    qualified domain names for users.
    I mounted the nfs4 ganesha's export using krb5.

    I create a file from client node logged in as us...@ad.domain.com
    <mailto:us...@ad.domain.com> but when I do "ls -I" I see below
    entries where as I expect the owner to be us...@ad.domain.com
    <mailto:us...@ad.domain.com>

    -rw-r--r-- 1         4294967294 4294967294 0 Aug  1 23:12 file1


    I see the below error in ganesha logs:


    nfs_req_creds :Could not map principal us...@ad.domain.com
    <mailto:us...@ad.domain.com> to uid


    I further went ahead and used nfs4_set_debug() to get more logs
    and found the below in ganesha logs when principal2uid() is called:

    nfs4_gss_princ_to_ids: calling nsswitch->princ_to_ids

    nss_getpwnam: name 'us...@ad.domain.com
    <mailto:us...@ad.domain.com>' domain '(null)': resulting localname
    'user1'

    nfs4_gss_princ_to_ids: nsswitch->princ_to_ids returned -2

    nfs4_gss_princ_to_ids: final return value is -2



    Relevant entries in my idmap.conf:

       [General]

    Domain = ad.domain.com <http://ad.domain.com>


    [Translation]

    Method = nsswitch



Did you try putting your domain in all caps in your idmap.conf?

    The same setup works if I disable fully qualified domain names
    from sssd.

    Is there a way to use other methods like umich_ldap and get Fully
    qualified AD domain  running with nfs4 ganesha?
    Can you please list the steps I need to follow on order to do that?


I'm not personally familiar with using AD.

Frank
