After successfully upgrading from version 5.0.2 to 5.4.1, Adclient goes into "disconnected" mode.Causes:
After upgrading adclient to 5.4.1, when adclient is binding to a Window Domain Controller 2003 (DFL 2003), it will fail the Machine password verification after retrieving the service ticket with the new machine password; therefore the
keyversionnumber from "/etc/krb5/krb5.keytab" is out of sync after the upgrade.Running "
adkeytab -C -m" does not allow the machine password to be reset.
[root@vanrh6-2 ~]# adkeytab -C -m
Error: Computer failed to change its own password
Adjust the privilege settings for 'vanrh6-2' or retry with a more privileged principal.
Failed: Change Password: Default Key Tab
1.)When upgrading from 5.0.2 to 5.4.x or above, please make sure adclient is binding to a DC which is Window Server 2008 or above in order to prevent adclient going into "disconnected" mode.
2.)If upgrading the Domain Controller to Window Server 2008 or above is not an available option, it is recommended to upgrade the adclient to a version that is no later than Suite 2013.2 (5.1.2).Note:
Below Platform support has been terminated in Suite 2015.1(5.2.3):
-Windows Server 2003
-Windows Server 2003 R2
