Privileges cisco-avpair = "shell:priv-lvl=10" doesn't work

Hi, I want assign different privileges to users, these are my users: admin Cleartext-Password := "admin" cisco-avpair = "shell:priv-lvl=15" user1 Cleartext-Password := "user1" cisco-avpair = "shell:priv-lvl=10" user2 Cleartext-Password := "user2" cisco-avpair = "shell:priv-lvl=11" But if I configure a privilege on my cisco switch on level 10, all my users have the same rights. If I debug on my switch, my user1 is not in priv lvl 10.. Any idea how to fix it? Grtz, Ruben
