When I connect my laptop to a SSID I set up on my Aruba network (currently consists of 2 APs, with a virtual controller shared between them), it successfully connects to the SSID but picks up the following IP:
My network consists of a Windows DC, acting as the DHCP server connected to a Cisco POE switch. Both the APs are connected to the same POE switch.
- All devices are on the same VLAN
- I've already configured options 43 and 60 in the Scope Options as per the guide here - http://community.arubanetworks.com/aruba/attachments/aruba/115/3411/1/DHCP_Microsoft_Option43-v1.1.pdf
- All devices have been statically assigned IPs and have entries registered in DNS (including the Aruba virtual controller)
- If I connect the laptop with an ethernet cable directly to the switch, it picks up a dynamically assigned IP on the correct VLAN
I'm racking my brains as to why my laptop can't see the DHCP server when on the WiFI.

Do you mean in Security > Users for Internal Server? If so, no, nothing is listed there. If not, can you explain where you mean? I'm fairly new to Aruba APs so will need a little hand-holding.

Niether, I chose "Network assigned" during the SSID setup, hoping this would pick up another DHCP server on the network.
As regards to the switch, all GigabitEthernet ports are on VLAN100. The Windows DHCP server is connected to port 1, the Aruba APs are plugged into ports 13 and 14, respectively.
Here's the switch port config I think you're after, with unused ports removed from the list:
Interface IP-Address OK? Method Status Protocol
Vlan100 10.60.100.12 YES manual up up
FastEthernet0 unassigned YES manual down down
GigabitEthernet0/1 unassigned YES unset up up
GigabitEthernet0/13 unassigned YES unset up up
GigabitEthernet0/14 unassigned YES unset up up
Please let me know if this is not the info you were hoping for.

I've recently started have kind of the same issue. But my issue is that it is sporadic. Say I have a IAP 135 with 3 users connected on it. One of the users gets the 169.254.x.x address while the other users have an IP in our coroporate DHCP range. The only way i have found to get the user with the "wrong" ip to pick up a valid dhcp IP is to reboot the IAP. Once it come back up they connect and get a valid DHCP IP.
What's weird is its not fixed to one particular IAP nor a particular client nor a particular timeframe, it varies around our IAP infrastucture (we have 38 of them managed by Airwave in 11 different geographic locations) all different times. We can go a few days without any issue, then it one day i have to reboot 3 devices.

Right, I did what you asked with the following details set for my own network but my laptop is still suffering from the same symptoms as before:
Helper address: 10.60.100.2
Any other suggestions I may have missed?
