  1. DCE Deployment at PSU Steven Kellogg Director, Advanced Information Technologies Center for Academic Computing kellogg@psu.edu

  2. WHY DCE? • We wanted DFS - DFS is better than AFS - File level ACLs - Byte-level locking, ( AFS is file level) • We wanted kerb5 • We wanted an integrated directory • We wanted a secure RPC

  3. WHY DCE?(cont’d) • Wanted an integrated management model • Integration of very heterogeneous systems • An extrapolation of skill base • We wanted an integrated authorization model • - DCE groups • - classes, orgs, admin functions...

  4. DCE Cell Status • ~75000 Principals • ~300 GB in DFS • AIX DCE 2.2 security and CDS servers • AIX, NT and OS/390 DFS fileservers • Clients - AIX, IRIX, NT, Solaris, OS/390

  5. Projects • Accounts Management Architecture - All new accounts added to DCE registry - Central user database - all people info - view of DB imported to LDAP - Automatic OHR, Registrar,.. Updates - Web based management tools: Gradient, IBM, RYO

  6. Projects (cont’d) • Account management architecture (cont’d) - Group management for group ACL’s - Every course and section - Faculty (location, college, dept) - Students (location, college, dept…) - Staff (location, college, dept..) - eg. CIS, EIS, Dept Web

  7. Projects (cont’d) • UNIX user accounts (integrated login) - DFS home directories • Financial Information Tool (FIT) - DCE RPC based C/S tool • TRICAAP - Inter-adapter junctioning - Many-to-one mapping

  8. Projects (cont’d) • OS/390 DCE/DFS - Secure, easy data sharing - Secure RPC’s • Digital Library - Built on DCE

  9. Projects (cont’d) • WEB Service - CAC: UNIX/Apache(DCEmod)/DFS - Personal, Dept, Groups, Courses (25K) - CAC, OHR: NT/NES/VB cgi/Gradient rte - OPP: Linux/Apache/Krb5libs - Library, EIS, C&IS, Purchasing:NT/ Gradient Sec.Adapter/NES or IE
