I am using OpenSuSE 12.1 with homes shared through LDAP and NFS.
ldap stores the maps.
My problem is I can't have the shares mounted on boot. It's only working when restarting the autofs service manually.
On a CentOS 6.3 there is no such problem.

My /etc/nsswitch.conf:

passwd: files sss

group:  files sss



hosts:  files mdns4_minimal [NOTFOUND=return] dns

networks:       files dns



services:       files

protocols:      files

rpc:            files

ethers:         files

netmasks:       files

netgroup:       files nis

publickey:      files



bootparams:     files

automount:      files ldap

aliases:        files

My /etc/openldap/ldap.conf:

SIZELIMIT       20

TIMELIMIT       15

#DEREF          never

TLS_REQCERT     demand

uri     ldap://10.0.0.1

base    dc=domain,dc=com

My /etc/sssd/sssd.conf:

[sssd]

config_file_version = 2

reconnection_retries = 3

sbus_timeout = 30

services = nss, pam

domains = domain.com



[nss]

filter_groups = root

filter_users = root

reconnection_retries = 3



[pam]

reconnection_retries = 3



[domain/domain.com]

 id_provider = ldap

 auth_provider = ldap

 min_id = 500

 max_id = 30000

 ldap_schema = rfc2307

 ldap_uri =  ldaps://ldap-ms.local,  ldaps://ldap-sl.local, ldap://ldap

 ldap_search_base = dc=domain,dc=com

 ldap_user_search_base =  ou=People,dc=domain,dc=com

 ldap_group_search_base = ou=Group,dc=domain,dc=com

 ldap_tls_cacert = /etc/pki/CA/certs/domain-cacert.pem

 ldap_tls_reqcert = hard

 cache_credentials = true

 enumerate = True

My /etc/sysconfig/autofs:

MASTER_MAP_NAME="auto.master"

TIMEOUT=300

BROWSE_MODE="yes"

MAP_OBJECT_CLASS="automountMap"

ENTRY_OBJECT_CLASS="automount"

MAP_ATTRIBUTE="ou"

ENTRY_ATTRIBUTE="cn"

VALUE_ATTRIBUTE="automountInformation"

USE_MISC_DEVICE="yes"

Am I missing something?

Why not just add the mount locations to your fstab.

You could also use sshfs.
Configure ssh to use public key authentication.

On the server:

sudo apt-get install openssh-server

Change to or add ServerKeyBits 2048 to /etc/ssh/sshd_config

On the Client

ssh-keygen -t rsa -b 2048

ssh-copy-id from the client computer to the server.
Use your password for your user on the server machine to login

Change /etc/ssh/sshd_config: PasswordAuthentication no, UsePAM no

I use other settings as well to harden ssh but for this example it is not needed.

If your outside your lan setup a dyndns or noip updater, and setup portforwarding on your router so port 23 or what ever port you decide to use to obfuscate the service is forwarded to the server ip address, if you need help with that just ask.

Then:

sshfs USER@SERVERADDRESS:/mnt/DRIVELOCATION /PATH/TO/MOUNT/DRIVE/TO

I set this command as a launcher on the main menu for some drives and for others in the fstab.

I know it works because I use this same setup plus the hardening everyday.

This way you can get rid of the need for autofs and its required overhead.

This question got bumped by community, and it's pretty old.

A lot of things has happened over the years, Michael mentioned one solution, using fstab. And the original problem was most likely do due execution-order at boot time. Network might not have been ready, some service might not have started etc.

There's also another solution if you're running systemd (which I doubt OP did at the time, but if you end up here through a search, and you do) here's another solution using systemd's automount feature.

[Unit]

Description=Network mapping

After=network.target



[Mount]

What=10.0.0.1:/share/stuff

Where=/mnt/remote_share

Type=nfs

Options=_netdev,auto



[Install]

WantedBy=multi-user.target

The only drawback of this is that you have to be careful with what you name the service script. It's best described here, but a tl;dr-version is that the service-file must be named after the path it's going to mount. And all forward-slashes in said path has to be replaced with - in the service-file name for automatic mounting to work. The above example of /mnt/remote_share would be a service-file calledmnt-remote_share.mount`

There's a bunch of options to go with this.

If systemd isn't your thing, there's also a lot of new stuff on the autofs side which does a pretty good job (all be it a bit complicated for my taste).

If you want to use a fstab entry instead but utilize systemd's auto-hook feature, here's what your fstab could look like:

10.0.0.1:/share/stuff   /mnt/remote_share  nfs  noauto,x-systemd.automount,x-systemd.device-timeout=10,timeo=14,x-systemd.idle-timeout=1min 0 0

And if neither of those work, there's also the pure-fstab solution:

10.0.0.1:/share/stuff   /mnt/remote_share   nfs   defaults,soft,rsize=32768,wsize=32768,timeo=900,retrans=5,_netdev 0 0

I'll drop a few links to good documentation on the subject (bare in mind, it's a different OS. But their Wiki is as of writing this one of the best on the market):

• https://wiki.archlinux.org/index.php/NFS#Mount_using_/etc/fstab_with_systemd


• https://wiki.archlinux.org/index.php/autofs

For any traveler across the internet ending up here, hope any of this helps.
