Hello,
I'm trying to automate freeipa-client installation on Ubuntu with custom script using MAAS as follow :
HOSTNAME=$(hostname)
IP=$(hostname -i | awk '{print $1}')
echo "$HOSTNAME.example.com" > /etc/hostname
FQDN="$HOSTNAME.example.com"
echo "FQDN is: $FQDN"
sed -i  "1 i\
$IP $FQDN $HOSTNAME" /etc/hosts
apt-get -y update
apt-get install -y nfs-kernel-server nfs-common
DEBIAN_FRONTEND=noninteractive apt-get -y install freeipa-client
ipa-client-install  --hostname=$(hostname -f) --server=freeipa.example.com --domain example.com --no-ntp --unattended --principal admin --password 'Deep201qa' --realm EXAMPLE.COM --enable-dns-updates
sed -i '/ticket_lifetime/a renew_lifetime = 28d' /etc/krb5.conf
service sssd restart

After the deployment i can do  kinit domain_user and ipa user-show without any problem, but when i tried to mount an nfs in /ec/fstab with the following options i get an error:
The  mount in /etc/fstab:  nfs4 rw,relatime,vers=4.2,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=krb5,local_lock=none 0 0
The error:
mount -av
/                        : ignored
none                     : ignored
mount.nfs4: timeout set for Wed May 29 20:04:29 2019
mount.nfs4: trying text-based options 'vers=4.2,rsize=1048576,wsize=1048576,namlen=255,soft,proto=tcp,timeo=600,retrans=2,sec=krb5,local_lock=none,addr=172.16.2.11,clientaddr=IP_ADDR0ESS

I tried to install  freeipa-client manually and the nfs mount works:
ipa-client-install

What i'm missing?

Thanks,
