Welcome screen content is not displayed for administrators who are mapped in via LDAP group

1. Configure Nexus to work against an LDAP server
2. Map an LDAP group into Nexus, granting it the "nx-admin" role
3. Log in using an LDAP user who is a member of the mapped group
4. Observe that no outreach content is displayed in the welcome screen

Logging shows that the request for content is made to "/en/user", rather than "/en/admin", as it should be:

 2018-01-11 14:23:44,178-0600 TRACE [qtp1270408041-220] rseddon com.sonatype.nexus.plugins.outreach.internal.outreach.SonatypeOutreach - checking remote http://links.sonatype.com/products/nexus/outreach/pro/3.7.0-02/en/user for bundle PageBundle{id='1187d1d14e0b30f4eeeb50b3827a1607d2c100dc'}

Expected: Administration outreach content should display for all Nexus administrators (anyone with nx-admin role), regardless of how they are mapped into Nexus.

Note: I tried the same test using a directly mapped LDAP user, and content is displayed.  So this only affects user mapped into Nexus via external role mapping.
