I CONFIGURE IN MY RFS7000 A VLAN POOL ASSIGMENT WITH AP7532, VLAN 190 Y VLAN 191, IS OK.
MY PROBLEM IS WHEN I TRY TO ASSIGN A IP WITH RESERVATION DHCP SERVER TROUGHT WIN SERVER 2013.

WIN SERVER ASSIGN 192,168.1.3 TO HOST. IN VLAN 190 WITH RESERVATION CONFIG.
BUT IN MY CONTROLLER ASSIGN VLAN 191 AND MY HOST DONT REACH THIS DHCP SERVER AND DONT GET THE IP 192.168.1.3 , TAKE IP FROM THE VLAN 191 ONLY 😞

HELP ME PLEASE.

Yes. You would need to setup the DHCP helper on your network...on VLAN-191. The helper would hear the DHCP Discovery broadcast messages and forward them to the DHCP server on VLAN-190 and the clients would then get an IP address while existing on VLAN-191.

This could also be accomplished using dynamic VLAN assignment and RADIUS.
When a client authenticates through RADIUS, the RADIUS server would be configured to provide a post-authentication VLAN ID using the tunnel-private-group-id attribute that is received by the controller in a RADIUS Access-Accept message.

In this case, you would have one SSID. When a user connects, that user's account on RADIUS could be configured so that it belongs to a specific VLAN. This obviously would require pre-configuring all of the users and mapping them to a desired VLAN. This is what the WLAN option in the GUI labeled "Allow RADIUS Override" is used for. If

When you setup a VLAN pool like this, the controller will evenly distribute the clients amongst the VLANs you have in the pool (round-robin). So it sounds like the controller is doing what it's supposed to do.

What you need to do is decide how you want to modify the the network so that clients are able to get a DHCP lease when connected to VLAN-191.
The first thought I have is to setup a DHCP helper/Relay agent on VLAN-191. This would allow clients on VLAN-191 to still Discover and Request IP addresses from the DHCP server that exist on VLAN-190.
