User names and passwords Not saving IE11 server 2012R2 & rds

hello all

hope someone can advise

i have just built a new RDS environment (with citrix xenapp 7.6) everything is working fine except for saving usernames and passwords. its really frustrating. our legacy environment is the same except using 2008R2 and that works fine

could someone advise on what needs to be saved in the local profile where these settings are saved ? is there a policy that needs setting specific for IE11 ?

 any advice appreciated

thanks

dave
