You can enable QOP strength options in the TD2, JWT, PROXY, and LDAP mechanisms, to use in enforcing QOP security policy. For information about how QOP strength options are used in QOP security policy, see Network Security Policy.

For users authenticated by Kerberos (KRB5 or SPNEGO mechanism) who enable message encryption or are subject to a confidentiality QOP policy, the system uses the encryption method and strength automatically negotiated by Kerberos. See Message Encryption for Kerberos Authentication.
