User group filter with & (and)/ |(or) and return attribute customisation

To implement PEM SSO current PEM can only use custom attribute / attribute with which can only return one string. Expected output as mentioned below.
Sample output user role:

</property><property><name>role</name><value>CN=SponsorAdmin,OU=Projects,OU=Groups,DC=xxx,DC=xxxx,DC=com</value></property>


Current requirement is AD team will have multiple groups created and have them added to memberof AD attribute. So, there is no static limit on number group that a user is part of. IBM PEM current configuration cannot accommodate this use case.

Below mentioned use case requires appropriate query with | (or) condition with & (and) to filter among multiple user roles specific to the application.
Had discussion with IBM SEAS team through IBM support ticket.

But L3 team has asked us to submit an enhancement request as this is not accomplished as part of the current application capability.
Sample output on Roche specific requirement:<name>prefferedLanguage</name> <value>US</value></property><property><name>role-1</name><value>CN=xxxx-xx,OU=xx,OU=xx,DC=xx,DC=xx,DC=com</value></property><property><name>role-10</name><value>CN=xx11,OU=xx,OU=xx,DC=xx,DC=xx,DC=com</value></property><property><name>role-11</name><value>CN=xx22,OU=xx,OU=xx,DC=xx,DC=xx,DC=com</value></property><property><name>role-12</name><value>CN=xx33,OU=xx,OU=xx,DC=xx,DC=xx,DC=com</value></property>

We would require capability to add | condition in the LDAP filter query which would allow us to compare multiple groups and also to return only the groups that are relevant to the query.
