'Could not chdir to home directory /home/[user]: Permission denied'
I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
login as: [me]
Last login: Wed Jan 6 18:34:33 2010 from [machine]
Could not chdir to home directory /home/[me]: Permission denied
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.
The problem is most likely related to the user and group IDs. When you create a user it is given a userid and a primary group ID. This information is stored in /etc/password normally (unless you use some form of network based authentication).
If you look at /etc/passwd you will see a number of user entries, below is a sample for some of the passwd file users on my system
The file is colon separated and the fields your interested in are the 3rd and the 4th. The 3rd field is the numeric user id for the user on this system and the 4th is the primary group ID for the user. You will probably find that when you look at the output from the command provided by Devnull10 that there are user ID's shown rather than usernames.
I am guessing the previous system on which the /home directories were originally created had assigned different user id's in the password file.
As devnull10 recommends the chown command can be used to change the owner and is probably a simpler way of fixing the access than trying to change the user ids in the /etc/passwd file because other files on the linux system will be using the new user id.
[jon@joshua11 /]$ ls -la /home/

The UID and GID in the /etc/passwd file is 500 for both. How can I find out what the UID and GID for the /home/jon directory is (as I assume this is the problem)? I have already done: -
chown -R 500:500 /home/jon
...but this doesn't seem to change the login problem, although I *do* have ownership of the files and directories as this user. Am I somehow missing changing the UID and GID for the hidden files even though the username is the same? Something that used the previous UID and GID in whatever scripts automatically moves your location to your home directory when you login?
Also, how come you have a separate group for your home directory? Seems a little strange unless you are wanting a limited set of other users to have some form of access?
That's the default setup for Fedora. Separate users and groups. Don't know why.
I've also done chgrp -R 500 /home/jon (and tried substituting "500" for "jon") to no effect. I have acces to the home directory as that user, just not able to automatically login to the home directory. It fails and I have to do "cd /home/jon" after logging in.
You could try creating a new home directory when logged in as root for the user jon. The following command will modify the user to have the home directory /home/jon_home (it will be created if it doesn't already exist). The -m flag will copy the contents of your existing home into the new directory.
Thanks Cardy - that shows a little more information on /home: -
drwx------. 32 500 500 4096 2010-01-06 19:52 jon
..but the numbers are 500 as they should be as listed in /etc/passwd: -
Running "cat /etc/fstab | grep /home" yields this, which is as it should be, I suppose: -
/dev/sdb1 /home ext3 defaults 2 1
The /home directory drive was 32-bit Fedora 11, the new system is 64-bit Fedora 12 in basically a new system. I just mounted the old drive and created users with the same names. Works fine as long as you don't mind manually cd'ing to your user home directory.
I couldn't see anything amiss with .bashrc or .bash_profile or anything like that, but it is definitely something to do with login.

Jan 6 22:53:51 joshua11 su: pam_unix(su-l:session): session opened for user root by jon(uid=500)
UID = 500, which is correct. Nothing in the messages log for the time it happened, nor in dmesg.
Very odd looking problem you have there. Could it be a SELinux context issue?
Try looking at the output of these:
# ls --context /home
# ls --context /home/jon
If not SELinux, it could also be an ACL issue. Try:
# getfacl /home
[root@joshua11 ~]# ls --context /home

Ah, this seems to show something different - the two directories I've added since I've run this drive (Platforms and Torrent-Files) from this new machine have different entries to the directories that were still there before - what does this mean?
