Two different security flavours in nfs mount auto.master

[Richard Smits <R.Smits@tudelft.nl>]

Hello,

I was wondering if the next example would be possible with the 
automounter. I have a feeling this is not possible, but maybe there are 
some options I do not know about.

I have two nfs servers.

One with /export with standard nfs export.

One with /export with krb5 security.

Now I want to moutn one of the two if a condition is met. The condition 
I check with the excecutable automounter script.

That is not my problem.

The problem is the auto.master file. For a directory, I can have one 
security flavour. This is my problem. I need two. See below :

# NFS homedirs
/home/nfs	/etc/auto.nfs -rw,-fstype=nfs --timeout 60

/home/nfs is the homedir for the user, I cannot change this because this 
is in the configuration os samba. (We use winbind for authentication).

But my auto.nfs script checks if the user has a homedir on the sandard 
nfs3 server, or has a home on our nfs4/krb5 server.

But my auto.master isn't ready for this if you know what I mean.

I need :

# NFS homedirs
/home/nfs	/etc/auto.nfs -rw,-fstype=nfs --timeout 60
/home/nfs	/etc/auto.nfs -rw,-fstype=nfs4,sec=krb5 --timeout 60

This does not work :-( I have tried this.

Any idea if this is possible with the automounter. I am currently 
looking at pam_mount, but the automounter has my preference.

Greetings .. Richard
