According to the following documentation, this is supported by the "System z Security Communication Server" used by the Identity Manager RACF connector:
LDAP Server Support for CSDATA (broadcom.com)
It is also possible to launch the native RACF command through such LDAP interface:
Native RACF command: ALTUSER <UXXXX> CSDATA(<attribute name>(<value>))
How to obtain the same result of the native RACF command, using IM?
We can manage CSDATA attributes in RACF V1 connector and in RACF V2 connector.
For RACF v2
Please see the section "Support for IBM Multi-Factor Authentication (MFA), NETVIEW and CSDATA segments of a user profile on z/OS systems." from below techdoc:
https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/identity-management-and-governance-connectors/1-0/connectors/ibm-connectors/ibm-racf/audience-file-location-for-the-racf-connector/feature-comparison-of-racf-and-racf-v2-connectors.html
From below techdoc, RACF v2 connector was enhanced to support IBM Multi-Factor Authentication (MFA), NETVIEW, and CSDATA segments of a user profile on z/OS systems
https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/identity-management-and-governance-connectors/1-0/connectors/ibm-connectors/ibm-racf.html
RACF v1 also supports CSDATA attributes (reagardless of the PTF being in place)
Please follow the documentation: https://ftpdocs.broadcom.com/cadocs/0/CA%20Identity%20Manager%20r12%205%20SP15-ENU/Bookshelf_Files/PDF/im_connectors_enu.pdf

The following document should be used as reference - LDAP Server Support for CSDATA and the configuration syntax expected in slapd.conf
Attributes need to be defined in slapd.conf – it should look similar to
##############################################################
# racf_utf database specific definition
# This definition is not for Identity Manager or Web Admin
###############################################################
database racf_utf
suffix "host=<hostname>,o=<org name>,c=<country>"
#keyword RACF LDAP type max_len display
user-csdata <att name> <att name> char 15
* max_len should be according to the custom attribute definition in the schema – the example below uses 15 for no specific reason.
