Quest (Vintela) Authentication Services (VASD) provides schema extensions to Active Directory to authentication against LDAP by providing SID to UID/GID mappings and vice versa. In multiprotocol environments that provide NFS and SMB protocols to the same underlying data it becomes tricky with permissions and file ownership since it must be maintained in the *nix and […]
A mixed protocol environment means that you have two means of accessing the same data generally through SMB/CIFS/Samba and NFS. SMB is natively supported in Windows and NFS is natively in *nix environments. There are complexities an organization will always run into when running in a mixed protocol environment which is a result of how […]
During testing, the EMC Isilon storage was successfully reading the Active Directory Attributes but the data was incorrect. The data that was in the uid & gid fields were id’s that were automatically generated by the Isilon storage itself. The id’s that were generated by the Isilon storage took precedence over any mappings that were […]
There are many challenges that are faced when an organization is forced to run a mixed protocol environment to serve up the same data. This introduces additional management tasks and additional complexities. In a mixed protocol environment you must manage Windows Access Control Lists (ACL) to enforce Windows permissions in addition to managing *nix user/group […]
