I have created a user ,in alfresco, with username employee1 and password also employee1. Then i have added some properties to alfresco-global.properties in order to sync users from AD. Then i created a user in AD with username: employee1 and password: P@$$w0rd. In Alfresco ,using admin account, i sent to this user some messages. Then, i logged in employee1 account using passwords employee1and P@$$w0rd. Both of this passwords lead me to one user (employee1), i know this, cause of the message that i have sent to him. One user in Alfresco have 2 passwords. How can i fix this problem?
