KB-8755: CentrifyDC fails to start due to a protection fault in libkrb5.so

Authentication Service ,  

26 May,17 at 07:08 PM

Applies to: Centrify DirectCOntrol 5.4.0 on all supported platforms

Problem:
1. The “service centrifydc start” command takes a long time to complete.
2. Domain logins are not working.
3. Syslog includes errors such as below:
Mar 31 17:48:54 ldt-1774089.gfdl.noaa.gov kernel: traps: adclient[6612] general protection ip:7fc9cd19a99d sp:7ffcb72c5aa8 error:0 in libkrb5.so.3.3[7fc9cd164000+c9000]

Cause:
There is a bug in the process that  does the cleanup of non fips entries.
For adclient, the key is generated with nonfips allowed enctype cannot be used with FIPS mode is enable.
As long as fips.mode.enable: true is set in centrifydc.conf once adclient is restarted, adclient will run in compliant mode.

Workaround:
Please set the following parameter to false in /etc/centrifydc/centrifydc.conf
adclient.krb5.keytab.clean.nonfip.enctypes : false

Resolution:
This issue is fixed in the 2017.1 release.
