CentOS7 Kerberos Auth:Kerberos 配置文件格式不正確;

  • May 3, 2017

我正在Squid 4.0為針對 Active Directory 域(Server 2012 R2)的基於組的 AD 身份驗證設置顯式代理,並在最小的 CentOS 7(64b)安裝上使用 SSL 碰撞。

域加入非常粗略,authconfig-tui但我設法將其基本配置為 AD 使用者可以通過身份驗證SSH,Squid 代理在身份驗證關閉的情況下工作。但kinit失敗:

[root@tc-icap squid]# kinit
kinit: Improper format of Kerberos configuration file while initializing Kerberos 5 library

在為 Squid 增加調試日誌並嘗試使用加入域的客戶端進行身份驗證後,我在 Squid 中看到了這一點cache.log

我真的找不到我的/etc/krb5.conf文件有什麼問題。我應該如何進行?

# Squid 4 Explicit Proxy Configuration File
# 
# Goals:
#   1. Install Minimal CentOS 7 VM to host Squid
#   2. Configure Squid for explicit proxying with the following features:
#      a. ICAP (Content Adaptation) integration with CA Data Protection 15.0
#      b. SSL Bumping (Peek and Splice -- Most recent and flexible configuration)
#      c. Active Directory / LDAP Authentication and filtering rules
#      d. User information pass-through to ICAP Agent (for mapping policy to authenticated users)
#      e. Attempt content blocking / data in motion capture
#   3. Test functionality of intercepting Outlook Anywhere connectivity (without breaking clients.)
#   4. AD Group based access control and possibly blacklisting
#   5. Integration with Windows Certificate Authority services to generate certs/key requests
#   6. Kerberos / WINBIND authentication if AD/LDAP doesn't work. (kinit/keychain issues currently)
#
# Nice to haves:
#   1. ECAP (Encrypted ICAP support.) Squid has this, ICAP Agent does not.
#   2. Debug why ICAP URI's fail with DNS entries instead of IP address
#   3. Test fail open / closed configurations
#   4. Experiment with transparent proxying of traffic (avoid end user proxy configuration)
#   5. ICAP Content Adaptation Chain (Squeeze ClamAV in before or after DataProtection agent)
#   6. Automated auto-configuration deployment
#   7. Inject custom web X-Headers, check if headers are available as XML Data Lookups in Data Protection
#
# Reminder:
#   1. Check and reload configuration changes in Squid without restarting via:
#      squid -k check
#      squid -k reconfigure

# Debug logging: (very noisy!)
