Hello,

currently i have SDP 10 synced with my AD on premises.

also we have Office 365 email service attached to the organization and uses the on premises AD to sync as well.

For this to work, In the AD, we have configured for every user the login option as:

- login: user

- login: user@o365email.com

well, back in the SDP, i just found that users can login via "user" and via " user@o365email.com" just if the AD password is correct.  This creates duplication in the requester and obviously every account got their own tickets.

i merged the accounts but this not solve the problem, because still users can log both ways.

i tried to deploy Single Sign On (i raised a ticket for that because it was not working properly), but this will not work until support helps me out.

my question is, i wonder if i can erradicate this problem blocking in the SDP login page the possibility of entering a user that uses @ character for example, if so, where can i do it? (like a blocked user = *@* for example).

Thanks!
