autofs mounts always get mounted on sudo. why ?

[john_farinelli at hp.com]

Hello,

We have an environment that uses autofs (dynamic mounts like automount). If I 
start with the system where non of the NFS mounts defined in our auto.direct 
file are mounted, then I run sudo, I find that ALL of the mounts are now 
mounted. I have checked the PATH variable for the user we are sudo-ing to, and 
find nothing that looks in these locations. Furthermore, if I "su -" to that 
user no NFS mounts get put in place.

We are using version : CU Sudo version 1.5.6p5.

Can anyone explain why this is happening and suggest a resolution ?

Thanks,

John Farinelli
