[sudo-users] Environment variables problem

[Joel GIROT]

Hi everybody

 

Please, can you help me ? (sudo novice)

 

I try to use sudo to switch between users who have differents environment
variables usually set at logon. Some of these variables are read only. To
actualize them, I try to suppress with sudoers file all variables beginning
with gvr_ :

If I use 

Defaults          env_delete+=gvr_*

The variables are erased but not deleted and still read only. Not good.

if I use 

Defaults          env_reset

Defaults          env_keep+=*, env_keep-=gvr_*

All variables remain.

 

I tried many ways and either all variables are deleted or either all
variables remain

 

Does somebody know the right syntax ?

 

Thanks in advance
