Resolution

CA LDAP started task acid was receiving security violations for CSFSERV(CSFDSG) which was valid because there was no PERMIT for it on the acid. Once you PERMITted the acid, the security violations went away.

According to the following IBM doc::

https://www.ibm.com/support/knowledgecenter/SSLTBW_1.13.0/com.ibm.zos.r13.gska100/csfserv.htm

CSFSERV(CSFDSG) authority is required for:
1. RSA Digital Signature Generation
2. ECC Digital Signature Generation

Since CA LDAP uses these services, the PERMITs for CSFSERV(CSFDSG) need to be given the to CA LDAP started task.
