Known Affected Releases
5.0(0.1) 5.0(0.21.1) 5.0(0.21.2) 5.0(0.21.3) 5.0(0.21.4) 5.0(0.21.5) 5.0(0.21.9) 5.2(0) 5.2(0.1) 5.2(0.2) 5.2(0.3)
Symptom: ACS 5.x self-signed certificate uses 512-bit key by default. If such a certificate is assigned for management, access with IE is no longer possible. This is because IE enforces a minimum 1024-bit key length for access to any SSL site (http://support.microsoft.com/kb/2661254). Conditions: ACS 5.x with 512-bit key length certificate for management. Use of IE as browser attempting access.
