Hello everyone, I initially followed freeipa NFS documentation for setting up external stand alone NFS server
ipa host-add mickey.corp.example.org ipa service-add nfs/mickey.corp.example.org ipa-getkeytab -s razoul.corp.example.org -p nfs/mickey.corp.example.org -k /tmp/nfs.keytab uploaded keytab to NFS server and all appeared to work just fine: mickey> export KRB5_CONFIG=/etc/nfs/krb5.conf mickey> kinit admin Password for ad...@corp.example.org: XXXXXXX mickey> klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: ad...@corp.example.org Valid starting Expires Service principal 05/16/2015 18:17:00 05/17/2015 18:16:50 krbtgt/corp.example....@corp.example.org mickey> kinit -k -t /etc/nfs/krb5.keytab nfs/mickey.corp.example....@corp.example.org mickey> klist Ticket cache: FILE:/tmp/krb5cc_0 Default principal: nfs/mickey.corp.example....@corp.example.org Valid starting Expires Service principal 05/16/2015 23:48:14 05/17/2015 23:48:13 krbtgt/corp.example....@corp.example.org mickey> However, I learned hard way (NFS stopped working) that ipa-getkeytab issues ticket with a default timeout of 3 months. I repeated ipa-getkeytab and got: mickey> kinit -k -t /etc/nfs/krb5.keytab kinit: Keytab contains no suitable keys for host/mickey.corp.example....@corp.example.org while getting initial credentials mickey> klist -k -t /etc/nfs/krb5.keytab Keytab name: FILE:/etc/nfs/krb5.keytab KVNO Timestamp Principal ---- ------------------- ------------------------------------------------------ 5 11/03/2015 10:50:10 nfs/mickey.corp.example....@corp.example.org 5 11/03/2015 10:50:10 nfs/mickey.corp.example....@corp.example.org 5 11/03/2015 10:50:10 nfs/mickey.corp.example....@corp.example.org 5 11/03/2015 10:50:10 nfs/mickey.corp.example....@corp.example.org When client tries to mount: # mount -vvv -o sec=krb5 mickey:/volume1/homes /mnt mount.nfs: timeout set for Thu Nov 5 11:41:39 2015 mount.nfs: trying text-based options 'sec=krb5,vers=4,addr=192.168.26.2,clientaddr=192.168.26.31' mount.nfs: mount(2): Invalid argument mount.nfs: an incorrect mount option was specified Not much information available...
