[SOLVED] autofs-ldap not mounting home shares

[Krusty Ruffle]

Background: I'm building a server to take care of central login information, etc in my home. I have to maintain a mixed windows/linux environment. So far I have LDAP taking care of logon information with samba for the windows machines. I am able to join the windows machines to the domain and logons work fine there, (though the Default User profile is not being used, but that is a different issue). On Linux machines, I am able to use the LDAP server to get logon information, but I cannot get it to automount the home directories.

I have followed the autofs-LDAP page at help.ubuntu.com (https://help.ubuntu.com/community/AutofsLDAP) but I see the following problems, all of which are on the client machine:

during boot up I get:
Starting automounter: loading autofs4 kernel module, no automount maps defined.

If I do sudo /etc/init.d/autofs reload I get:
Reloading automounter: checking for changes ...
Started automounter: /home

and with cat /var/log/syslog | grep auto I get:
automount[6371]: lookup(ldap): query failed for (objectclass=nisObject): No such object
automount[6371]: lookup(ldap): query failed for (objectclass=automount): No such object
automount[6371]: failed to load map, exiting

ldapsearch -x from the same machine gives me, (this is trimmed down and names have been editted etc..):

I've been searching the net for several days trying to resolve this, any help is greatly appreciated...

Okay, I figured this out.
First I added the home directories to the /etc/exports file, then I backed up the ldap database with ldapsearch -x >> ldap.ldif Then I wiped out the entire database with sudo rm /var/lib/ldap/*db Restarted the server with:sudo /etc/init.d/slapd restartEdited the ldap.ldif file I had just created to take out the automount related stuff I posted in the preivious post and added the following, (using the propper domain/user names, etc...):# auto.master, mydomain.name
dn: ou=auto.master,dc=mydomain,dc=name
objectClass: top
objectClass: automountMap
ou: auto.master

# /home, auto.master, mydomain.name
dn: cn=/home,ou=auto.master,dc=mydomain,dc=name
objectClass: automount
cn: /home
automountInformation: ldap ldap.mydomain.name:ou=auto.home,dc=mydomain,dc=nam e

# auto.home, mydomain.name
dn: ou=auto.home,dc=mydomain,dc=name
objectClass: top
objectClass: automountMap
ou: auto.home

# loginname, auto.home, mydomain.name
dn: cn=loginname,ou=auto.home,dc=mydomain,dc=name
objectClass: automount
cn: loginname
automountInformation: -fstype=nfs,hard,intr,nodev,nosuid nfs.mydomain.name:/home/loginnameAnd used ldapadd to import the .ldap.ldif file and now it works!!

Note: I did have to enable the rootdn and rootpw in /ets/ldap/slapd.conf to get past some authentication errors before I could do re-enter the information into the database, then I had to fix all of the user passwords and stuff, but that was all stuff I already learned how to do before I could even get this far....

Hi Guys,

Thanks for the post. It helped me a lot.

But just one more thing to make clear:

#/home, auto.master, mydomain.name
dn: cn=/home,ou=auto.master,dc=mydomain,dc=name
objectClass: automount
cn: /home
automountInformation: ldap ldap.mydomain.name:ou=auto.home,dc=mydomain,dc=nam e



The bold faced line above actually should be:

automountInformation: ldap://ldap.mydomain.name/ou=auto.home,dc=mydomain,dc=name


Where ldap.mydomain.name is your LDAP server and it may be a static IP address such as:

automountInformation: ldap://192.168.20.2/ou=auto.home,dc=mydomain,dc=name



Please don't forget the ldap://whatevre-may-be/ part, otherwise your configuration may not work every where such as Scientific Linux 5 which was my case.

It works fine both in SL 5 and Kubuntu Hardy. Thanks again for the post.

Hi,

I'm trying to mount home directories and having the auto.home and auto.master in the ldap tree. I can login as a ldap user and I am able to mount manually the home folder. When I login a home directory is created in the location I set in the ldap tree under the user. What I am wondering is where can I look for information as to what is wrong? As in is there any log that might be able to provide information as to what is wrong? Thanks for your help!

Hi WeyOh,
I am not an expert or something in Linux but I learn something that I want to share. The following command on Kubuntu, which is one of my workstations, helped me a lot:

sudo /etc/init.d/autofs status

It tells me the following

Configured Mount Points:
------------------------
/usr/sbin/automount --timout=300 /vhome ldap://192.168.93.199/ou=auto,vhome,dc=domain,dc=com

Active Mount Points:
----------------------
/usr/sbin/automount --pid-file=/var/run/autofs/_vhome.pid --timount=300 /vhome ldap://192.168.93.199/ou=auto.home,dc=domain,dc=com


where 192.168.93.199 is my LDAP server, /vhome is the directory where my LDAP users' home directory are mounted.

Please note that I faced a problem with mounting the home directories on /home because (I guess) my /home was on a separate partition.

Thanks for your reply, I had a look and effectively I don't have my mount point in the configured mount point list. I don't know what to do. I followed everything that was said above. As I said earlier I can login perfectly but I am running into trouble when I have to mount the directory. Any suggestions? Any data that I could post to give you guys an idea of the problem? Thanks!

Ok, so after a lot of playing I came accross something weird, when I do:
sh -x /etc/init.d/autofs start
After some configuration settings I get this
/etc/init.d/autofs: 122: Syntax error: "(" unexpected

Which corresponds to
function getschemes()
{
SOURCES=`grep ^automount: /etc/nsswitch.conf | \
sed -e 's/^.*://' -e 's/\[.*\]/ /g'`

if [ `echo $SOURCES | awk '{print NF}'` -gt 0 ]
then
echo ${SOURCES}
else
echo files
fi
}
I have no clue what to do now. Any ideas?

Hi, while I am still having problems with mounting an auto.direct map. I do have a answer for the problem above. The problem is a syntax error when defining the functions in the shell script. The author of the shell script uses

function getschemes ()

I think that is a perl syntax, it ain't shell. The correct syntax is

getschemes ()

there were 15 functions called like this in the shell script by my count. You will need to edit the script and correct the syntax error for each funcion. I would recommend you make a copy of the original script before you start editing in case you get confused and need to start over from the beginning.

If you know a little bit about vi this should do it from the ex command line

:%s/^function //

I am still having issues with the auto.direct map, but this should cure the error you were describing.
