[CentOS] poppassd and different password

hello centos network

I installed poppassd (the deposit razor edge) to change easily passwords of users of my system I allow connections on port 106 that locally I have configured pam I did install the plugin roundcubemail password in webmail everything seems to work well

my question is simple

on my system for some users, I built chrooted

well I manage to change the password of users with the interface roundcubemail webmail but I wonder if the password and changes in the chroot or also to the outside of the chroot

question may seem stupid but I do not know ... any comments are welcome

sincerely nb: Happy New Year
