New Post: People Picker Not working with one-Way trust Domain

We have 3 Forest,

A=Internal
B=External
C=DMZ

we Have two way Trust from C to A and C to B and one Way Trust for B to A our Adfs is installed on DMZ & SharePoint is installed on C

now i can pick B=External Domain account but not A=Internal Domain Account. When i use Windows Authentication its work fine.

anything we need to change in LDAPCP Solution for this?

Thanks
