@iarspider , can you please also backport it to 10.6.X ?

[iarspider]

@smuzaffar 10_6 currently has XRootD 4.8.5, and if I'm not mistaken you instructed me to backport to versions that have 5.x . If that's fine, I will prepare the backport

UPD: I see that backport was explicitly requested link, on it.

why you say that? it should have 5.x version already

@iarspider , 13.0.X is also already using xrootd 5.x so please open a backport for 13.0.X too
