[SOLVED] procedures for mounting nfs3 ldap home directories using autofs on rhel6/centos6

HuMan-BiEnG · 07-18-2014, 09:34 PM

Hello there,
i'm practicing on mounting ldap home directories within autofs
actually i have two virtual machines one as server & other as client
the server has ldap server with home directories exported within NFS3 but not properly configured !!
as i got this error when trying to mount ldap home directories :

Code:

[root@exam01 ldapusr01]# getent passwd ldapusr01
ldapusr01:*:600:600:ldapusr01 ldapusr01:/home/ldapusr01 :/bin/bash
[root@exam01 ldapusr01]# su - ldapusr01
su: warning: cannot change directory to /home/ldapusr01 : No such file or directory
id: cannot find name for group ID 600
-bash: [: /home/ldapusr01: binary operator expected
-bash-4.1$

i know that the problem with NFS on the server machine but unfortunately i dont have time for fixing this issue
anyway this prevents me from getting the right procedures for mounting ldap home directories within NFS3 !!
so, i just want someone to help me by confirming that i'm using the right procedures
i use the following practice :

Code:

Configure autofs requirement :
a. serv1.lab (192.168.3.1) NFS 3 – exports /rhome for ldapuser03
b. ldapuser03 home directory is serv1.lab:/rhome/ldapuser03
c. ldapuser03 home directory should be auto mounted locally beneath /rhome as /rhome/ldapuser03
d. home directories must be writable by their users

i will will solve this by the following procedures :

Code:

1) enable nfs 
yum -y install nfs-utils
2) check/install autofs
(rpm -qa | grep ^autofs) || yum -y install autofs
chkconfig autofs on
3) create automount entry
echo "/rhome   /etc/auto.ldap" >> /etc/auto.master
echo "ldapuser03  -fstype=nfs,nfsvers=3,rw,sync serv1.lab:/rhome/ldapuser03" > /etc/auto.ldap
4) restart autofs 
/etc/init.d/autofs stop && /etc/init.d/autofs start
5) confirm mounting ldap home directory
su - ldapuser03

because i have problems in configuring NFS on the server machine i didnt know wether i'm right or wrong

so please can anyone confirm the previous procedures ?
am i right using the options "-fstype=nfs,nfsvers=3" for mounting NFS 3 ?
any help will be appreciated,
please all accept my best regards,,

Code:

ldapusr01:*:600:600:ldapusr01 ldapusr01:/home/ldapusr01 :/bin/bash

What happens when you remove the space after /home/ldapusr01?

Hello AlucardZero,
i have reinstalled server machine & reconfigured nfs & ldap server
but still have the same problem , as shown :

Code:

[root@localhost ~]# getent passwd ldapusr01
ldapusr01:*:6000:6000:ldapusr01 ldapusr01:/home/ldapusr01:/bin/bash
[root@localhost ~]# su - ldapusr01
su: warning: cannot change directory to /home/ldapusr01: No such file or directory
id: cannot find name for group ID 6000
-bash-4.1$

the problem is with configuring "automount" option within ldap server which needs more time in order to get fixed
unfortunately i dont have more time for investigating ldap automount options

thanks man for your trying to help & i relly appreciate this so much
anyone please could confirm the solution/procedures for mounting ldap home directories !!!!
please all accept my best regards,,,

Code:

echo "/rhome   /etc/auto.ldap" >> /etc/auto.master

You are automounting the LDAP homedirs under /rhome, but your passwd information has /home/ldapusr01.

Change /home/ldapusr01 to /rhome/ldapusr01 and make sure /rhome directory is created on the client, OR change "/rhome /etc/auto.ldap" to "/home /etc/auto.ldap", make sure nothing else is mounted on /home, and restart autofs.

Hello AlucardZero,
i have no time to retry again also am pretty sure that this problem could be fixed from ldap server
by configuring "automount" option !!

i just need to be sure from options for mounting ldap home directories within NFS v3 using autofs
are the following options are right for this :

Code:

ldapuser01      -fstype=nfs,nfsvers=3,rw   serv1.lab:/rhome/ldapuser01

just need to be sure from this options
can anyone here confirm these options !!
thanks again AlucardZero
please all accept my best regards,,

Sure. But you're still going to get "No such file or directory" until you fix the client as in my previous post.

It's like you're at 101 Independence Ave but then told your grandparents to meet you at 1600 Pennsylvania Ave. They're not going to find you.

Hello AlucardZero,
first thank you man for insisting to help me
& be sure man that mee too want to help myself
when investigating this problem i found that there is a "automount" option that should be configured within ldap ldif files
but i didnt configured & sure this is the root cause of the problem
i have reconfigured ldap server for home directories under "serv1.lab:/rhome/ldapusr0X"
then in the client machine i have configured it to mount ldap home directories under "/rhome/ldapusr0X"
as you asked for but this doesnt also solve the problem
this makes that the root cause in ldap automount configuration option as i told you before
thats why i was trying to make things easy by getting the right options for mounting nfs 3
anyway many thanks man for trying to help me

time is over & hope that i used the right options for mounting ldap nfs 3 home directories
please accept my best regards,,
