What are supported ciphers for CA LDAP on the Mainframe?
Release : 15.0
Component : LDAP Server for z/OS
The cipher suites that are available are based on the IBM System SSL component. These can then be specified in slapd.conf for CA LDAP.
A list of examples are provided in the CA LDAP documentation under Customize the Slapd Configuration File > TLSCipherSuite
Note that the list of ciphers in the documentation are just examples so that a site can appropriately make changes to the configuration file. The IBM System SSL component is what determines whether or not a cipher is supported, CA LDAP passes on the information for allowed ciphers to the IBM component.
