What is Azure AD Connect

Azure AD Connect
Azure AD Connect is a tool that connects functionalities of its two predecessors –  Windows Azure Active Directory Sync, commonly referred to as DirSync, and Azure AD Sync (AAD Sync). Azure AD Connect will be now the only directory synchronization tool supported by Microsoft as DirSync and AAD Sync are deprecated and supported only until April 13, 2017.
Why do you need Azure AD Connect?  
To synchronize users’ identities between local and cloud directories. Here "local" refers to the on-premise Active Directory infrastructure and domains and "cloud" refers to the applications hosted in Azure cloud, such as Office 365 or O365.
Why do you need to synchronize between local or on-premise Active Directory and Azure AD?  
To provide for users access different resources on both on-premises and cloud environments with just a single set of credentials. Applications that are deployed in a traditional Data Center or on-premise rely on the on-premise AD for authentication whereas Applications deployed in the cloud depend upon Azure AD.
For this synch to work you need to use Azure AD Connect to integrate your on-premises Active Directory with Azure AD.

 See diagram below
The user shown in the above diagram can access or sign-in to both applications, deployed in (a) Azure cloud and (b) applications hosted on-premise, shown as On-premises Sign-on and Cloud Sign-on arrows.

VMware fix for Invalid manifest and ova file import failed errors

Image
Recently we got a OVA file for a virtual machine. The vendor instructions were to import the ova file in vmware Workstation, Player for Windows/Linux, Fusion for Mac, and VirtualBox as well.  The instructions were to take the available package and launch the VM with VMware workstation. The package contained  Module.mf, Module.ovf and Module-disk.vmdk and a Module.ova file. The .mf and .ovf file were 2 KB each whereas the vmdk was several gigs. The package also contained a Module.ova file which was several gigs as well. OVF           Open Virtualization Format MF             Manifest file VMDK       Virtual Machine Disk OVA           Open Virtualization Appliance The ovf file is a xml file that contains metadata for the ovf package The mf file contains the SHA1 hash codes of all files in the package The vmdk file is the disk image of the virtual machine,  VMware Workstation or VirtualBox.

Note: SoapUI has two versions, one is open source and second Professional version. The open source can be download here . (confirmed link 12/19/2018). SSL Handshake issue:   There is an Issue in SoapUI version 5.3.0 (and 5.2.0 version) with SSL handshake error. It was resolved by updating below in vmoptions file ( refer here ). However, the error that shows up while trying to load wsdl is "Error loading WSDL" as below The fix is to Enable TLS 1.2 protocol for SOAP/REST calls in SoapUI, by ammending the vmoptions file to add the directive for TLS as (-Dsoapui.https.protocols=TLSv1.2). Refer here . Update: Version 5.5.0 does not have this issue. If you are on 5.3.0 better upgrade to 5.5.0 which is available now (Feb 2019). I had above issue as well as another issue reaching to https endpoint. Upgrade to 5.5.0 resolved issue. Select "Check for updates" under the Help menu and you will get option for upgrade.

Centrally Managed Users (CMU) - New Feature in Oracle Database 18c

Image
Centrally Managed Users (CMU) Centrally Managed Users or CMU is a new feature introduced since Oracle DB 18c which allows simplified database user management through integration with Microsoft Active Directory (AD). Beginning with Oracle Database release 18c, version 18.1 and later supports direct integration with Microsoft Active Directory (AD) using the new centrally managed users capability. CMU allows the Oracle database to perform user authentication and authorization directly against AD. Benefits of CMU With centrally managed users, users accessing the database can be centrally managed to improve an organization's security posture. An enterprise user (a user in Microsoft Active Directory) can be exclusively mapped to a database account, or many enterprise users (in an Microsoft Active Directory group) can be mapped to a shared account in the database. Microsoft Active Directory groups can also be mapped to a database global role, which provides users with additional privilege
