I'm using Autofs and LDAP for mounting my home directories via nfs. In general, everything seems to work fine. However, I have one small problem. If I reboot my server using autofs while my LDAP server is down, I get the following error message in my logs:
I can't help you - but can you help me by pointing me to the docs you used to get this far?
Holy cow. It wasn't easy... I had to do a lot of digging around to find the necessary stuff, and unfortunately, don't have all the links any more. I did a lot of searching online using LDAP and autofs as query strings. Some of the links I found were the following that helped me understand. Mind you, none were "howto" recepies as such.

In a nutshell (if memory serves properly), you needed to do the following (this is all assuming you already have a functional LDAP server up and running and properly configured in your nsswitch.conf files and your ldap.conf files, etc).
1) Add the autofs schema to your ldap server (add the following line to the slapd.conf file: include /etc/openldap/schema/redhat/autofs.schema). I don't remember if I already had the autofs.schema file or not, or if I had to search for it.
2) Modify your /etc/sysconfig/autofs to uncomment: # MAP_OBJECT_CLASS="automountMap" ENTRY_OBJECT_CLASS="automount" MAP_ATTRIBUTE="ou" ENTRY_ATTRIBUTE="cn" VALUE_ATTRIBUTE="automountInformation"
3) Create an ldif file and import into your LDAP server to show the following. Note, that my NFS server has the home directories located at /var/nfs/home/<user name>. Your mapping may be different.
dn: ou=auto.home,dc=domain,dc=com objectClass: top objectClass: automountMap ou: auto.home
dn: cn=/,ou=auto.home,dc=domain,dc=com objectClass: automount cn: / automountInformation: -rsize=8192,wsize=8192,intr nfs_server.domain.com:/var/nfs/home/&
dn: ou=auto.master,dc=domain,dc=com objectClass: top objectClass: automountMap ou: auto.master
dn: cn=/home,ou=auto.master,dc=domain,dc=com objectClass: automount cn: /home automountInformation: ldap:ldap_server.domain.com:ou=auto.home,dc=domain,dc=com
4) Cross your fingers and restart your ldap server and your autofs daemon and hope it works. I got this working on CentOS 5.3.
Hope this helps. I remember having to do a lot of digging around, a lot of searching and a lot of trial and error to get it working. But hopefully the above points should at least set you off in the correct path. Keep in mind I am by far no expert - I just poked around until I got it working, and once I did, stepped away from it.
Good luck.
