Introduction I've been curious from some time to see how Active Directory users could natively authenticate to Linux, or said in a different way, how to configure Linux to allow AD users to log in without the need to have those users in each and every Linux box manually. Although there are several different ways to accomplish this, I found that the easiest and less time consuming way to do it is with the use of Samba WinBind. Later I will show how to use Oracle Internet Directory (OID) to accomplish the same feat. Using an IdM solution (AD, OID) can help to reduce the time to deploy users, you can centrally manage access to linux servers from Active Directory Users and Computers (ADUC) app, and can allow administrative tasks thru sudo depending on the group the users belong to. For my Proof of Concept I created two virtual machines, one with Windows 2012 Server Essentials, and another one with Oracle Linux 7.1. In AD I created 1 group named osd-linux-oretail, and several tes
I ran into an issue with a recently cloned database. Every time I ran "resync catalog from db_unique_name all;" command in RMAN, it error out with RMAN-6613: connect identifier for db_unique_name not configured. We know that this command is not needed for non-dg enabled databases, but because we have a mix of DG and non-DG enabled databases, maintaining different scripts per type of database is not worth it. To the extent of my knowledge, this command is harmless; the error is more like a warning on non-dg databases, still is a symptom of something not well configured. Troubleshooting Once you connect to the target and catalog repository with RMAN, you try to resync catalog with the following command: RMAN> resync catalog FROM DB_UNIQUE_NAME ALL; starting full resync of recovery catalog full resync complete resyncing from database with DB_UNIQUE_NAME DBTST RMAN-00571: =========================================================== RMAN-00569: =============== ERROR MESSAGE
