[SSSD] SSSD netgroup issue

[Francisco Javier Marín Murillo]

Hello,
 
I have this nsswitch configuration:
 
passwd: compat
passwd_compat:  sss
#shadow: files ldap
#group:  files ldap

#passwd:     files sss
#passwd:            compat sss
shadow:     files sss
group:      files sss

hosts:      files dns
bootparams: files
ethers:     files
netmasks:   files
networks:   files
protocols:  files
rpc:        files
services:   files
netgroup:   sss
publickey:  nisplus
automount:  files ldap
aliases:    files
sudoers:    files ldap 
 
 
Currently I am having problems with sssd handling netgroup changes.
 
when I add or remove a user from a netgroup , those changes are not replicated
automatically to clients . Should be something wrong with my sssd.conf configuration ? 
 
If you can give me a hand I would really appreciate it.
 
Thanks,
 
Francisco Marin
