Hi, I followed this instruction http://www.gluu.org/docs/admin-guide/installation/centos/ and installed the gluu server on CentOS 6.5 today ( 10/21 ). The server is up and running. I went to https://ce.gluu.info and login as admin. I went to Users / Manage People / Add Person. I put in username, first name, display name, last name and email. Then clicked on the Add button ( I thought this is the save button ). Then I logged out and logged in again, went to Users / Manage People. I searched by username, first name and last name, could not find the people I added in before. Question 1: Is there manual to teach how to use the UI? Question 2: Where are the log files? Sometime I wonder if the gluu server works properly, I want to check the logs to see if there is error message. =========== error inside oxtrust.log ==================== 2014-10-21 17:22:40,374 DEBUG [org.gluu.oxtrust.ldap.service.AppInitializer] Created site LdapEntryManager: org.gluu.site.ldap.persistence.LdapEntryManager@4f305b04 2014-10-21 17:22:40,414 ERROR [org.gluu.oxtrust.config.OxTrustConfiguration] Failed to load configuration from LDAP 2014-10-21 17:22:40,414 WARN [org.gluu.oxtrust.config.OxTrustConfiguration] Unable to find configuration in LDAP, try to create configuration entry in LDAP... ... 2014-10-21 17:42:35,939 DEBUG [org.gluu.oxtrust.ldap.service.MetadataValidationTimer] Metadata validation finished 2014-10-21 17:42:46,729 ERROR [org.gluu.oxtrust.action.UpdatePersonAction] Failed to add new person @!59C3.86F5.B294.BA10!0001!8EAA.6A7B!0000!3F41.2E24 org.gluu.site.ldap.persistence.exception.EntryPersistenceException: Failed to persist entry: inum=@!59C3.86F5.B294.BA10!0001!8EAA.6A7B!0000!3F41.2E24,ou=people,o=@!59C3.86F5.B294.BA10!0001!8EAA.6A7B,o=gluu at org.gluu.site.ldap.persistence.LdapEntryManager.persist(LdapEntryManager.java:82) at org.gluu.site.ldap.persistence.AbstractEntryManager.persist(AbstractEntryManager.java:94) at org.gluu.oxtrust.ldap.service.PersonService.addPerson(PersonService.java:81) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) ...
