Description
IPA 3.0 includes a tool that can be used to configure automount.
There are two ways to configure automount:
* Using the autofs client * Using sssd
IPA defaults to using sssd for automount.
Setup
- Make sure you have a working FreeIPA server
- You will need an enrolled client
How to test
Configure an NFS server
In order to test we need an NFS server to test against.
We will configure the IPA server as an NFS server. You will need to install these packages:
# yum install nfs-utils
Edit /etc/idmapd.conf and set Domain to your domain (example.com)
Create /etc/exports with the following content:
/ipaexport *(rw,sec=sys:krb5:krb5i:krb5p)
Note: you may want add the insecure option so that ports > 1024 can access the mount.
Create the export
# mkdir /ipaexport # touch /ipaexport/hello
Export the files:
# exportfs -fva
Create the IPA nfs service:
# kinit admin # ipa service-add nfs/ipaserver.example.com # ipa-getkeytab -s ipaserver.example.com -k /etc/krb5.keytab -p nfs/ipaserver.example.com
Start NFS:
# service nfs-secure restart # service nfs-server restart # service nfs-secure-server restart
Configure IPA automount
IPA lets you have different automount maps for different locations. The default location is 'default'. We'll use that.
Add a map to test with:
# ipa automountmap-add-indirect default ipaexport --mount=/ipaexport
Create an automount key:
# ipa automountkey-add default ipaexport --key=test --info='-fstype=nfs4,rw,sec=krb5,soft,rsize=8192,wsize=8192 ipaserver.example.com:/ipaexport'
Client test with SSSD
Run the IPA automount configuration tool, accepting default options:
# ipa-client-automount Searching for IPA server... IPA server: ipaserver.example.com Location: default Continue to configure the system with these values? [no]: y Configured /etc/nsswitch.conf Configured /etc/sysconfig/nfs Configured /etc/idmapd.conf Started nfs-idmap.service Started nfs-secure.service Restarting sssd, waiting for it to become available. Started autofs.service
Test the mount:
# kinit admin # ls /ipaexport/test hello
Test uninstall
The uninstaller does not automatically unmount existing mounts.
# ipa-client-automount --uninstall # umount /ipaexport/test # ls /ipaexport/test
Expected response:
ls: cannot access /ipaexport/test: No such file or directory
Client test with autofs
Restart SSSD so it knows it no longer controls automount:
# service sssd restart
Run the IPA automount configuration tool, accepting default options:
# ipa-client-automount -S Searching for IPA server... IPA server: ipaserver.example.com Location: default Continue to configure the system with these values? [no]: y Configured /etc/nsswitch.conf Configured /etc/sysconfig/nfs Configured /etc/idmapd.conf Started nfs-idmap.service Started nfs-secure.service Configured /etc/autofs_ldap_auth.conf Configured /etc/sysconfig/autofs Started autofs.service
Test the mount:
# ls /ipaexport/test hello
Test uninstall
The uninstaller does not automatically unmount existing mounts.
# ipa-client-automount --uninstall # umount /ipaexport/test # ls /ipaexport/test
Expected response:
ls: cannot access /ipaexport/test: No such file or directory
Expected Results
All the test steps should end with the specified results.
