LDAP group search filter

in Community 9.5…is there any way to modify how CentraSite builds the filter for group search query against LDAP?

this is what it is using but we have issues with name format in our LDAP and was wondering if we could change how this query is built.

[authldap] | ssx_ldap_searchW : Filter : (&(objectClass=group)(member=CN=first.last,OU=IT,OU=,DC=*,DC=com))
