Hi dotnetteramg123,
I would suggest you create a new Organisation Unit called "MSCRM" and select it for the install. Please make sure the installing user has full permissions to this OU in the Active Directory. During the CRM install it will create 4 security groups
and put them inside this OU. Dynamics CRM 2011 installs 4 Active Directory Security Groups (PrivReportingGroup, SQLAccessGroup, ReportingGroup and PrivUserGroup
The following is for CRM 2011 and from the below link, that should be the same for CRM 2013 too.

As part of the installation of Microsoft Dynamics CRM 2011, the setup program requires the input of a domain organization unit in which the CRM security objects will be created. Although this organization unit may be any container in the domain hierarchy,
it is recommended that you define a dedicated container for these objects for manageability. Also, you should consider locating this container in the domain hierarchy to limit access to other domain resources for CRM services and functionality enabled under
these credentials.
For example, you may create an organization unit named "CRM Security Groups," and select that container during the CRM setup procedure. Upon install, CRM will create four security groups for the CRM deployment in that organizational unit. Each security group
will contain the GUID of the CRM deployment as part of the name.
If you plan to install multiple CRM deployment groups in the domain, mapping the security groups to the CRM deployment group may be challenging. Consider performing the following:
- Prior to installing CRM, create unique organization units for each is CRM deployment group, to isolate the security objects during the install. Each container will include only the security groups related to that CRM deployment group.
- After installing CRM, update the description of the security groups with an easily identifiable value to create the mapping. This value is then displayed in Active Directory Users and Computers for easier identification.
