Hello, I am having the exact same problem as described [here](https://support.gluu.org/view/installation/unable-to-login-using-admin-user-id-password/1655). I followed the instructions from this [post](http://www.gluu.org/docs/admin-guide/installation/ubuntu/), installing gluu-server_2.0-0_amd64.deb and cannot login with the 'admin' user after the installation. Many thanks in advance, My log: 2015-03-23 23:20:27,722 DEBUG [org.xdi.oxauth.service.AuthenticationService] Authenticating user with LDAP: username: admin 2015-03-23 23:20:27,724 DEBUG [org.xdi.oxauth.service.AuthenticationService] Attempting to find userDN by primary key: 'uid' and key value: 'admin' 2015-03-23 23:20:27,725 DEBUG [org.xdi.oxauth.service.AuthenticationService] Getting user information from LDAP: attributeName = 'uid', attributeValue = 'admin' 2015-03-23 23:20:27,796 DEBUG [org.xdi.oxauth.service.AuthenticationService] Found '1' entries 2015-03-23 23:20:27,809 DEBUG [org.xdi.oxauth.service.AuthenticationService] Attempting to authenticate userDN: inum=@!B203.1449.55C0.7929!0001!FC3F.135C!0000!A8F2.DE1E.D7FB,ou=people,o=@!B203.1449.55C0.7929!0001!FC3F.135C,o=gluu 2015-03-23 23:20:27,873 DEBUG [org.xdi.oxauth.service.AuthenticationService] User authenticated: inum=@!B203.1449.55C0.7929!0001!FC3F.135C!0000!A8F2.DE1E.D7FB,ou=people,o=@!B203.1449.55C0.7929!0001!FC3F.135C,o=gluu 2015-03-23 23:20:27,873 DEBUG [org.xdi.oxauth.service.AuthenticationService] Attempting to find userDN by local primary key: uid 2015-03-23 23:20:27,876 DEBUG [org.xdi.oxauth.service.UserService] Getting user information from LDAP: attributeName = 'uid', attributeValue = 'admin' 2015-03-23 23:20:27,888 DEBUG [org.xdi.oxauth.service.UserService] Found '0' entries 2015-03-23 23:20:27,890 INFO [org.xdi.oxauth.auth.Authenticator] Authentication failed for admin
