Authentication with EAP-MD5/PEAP/FAST

Question

Version: ISE 1.2p12
Hello,
I have trouble authenticating devices that use different protocols:
- Cisco IP Phones: EAP-MD5
- Windows machines: EAP-PEAP
- Cisco APs: EAP-FAST
1) I'm able to authenticate the IP Phones individually with a authentication rule:
IP PHONES If Wired_802.1X allowed protocols EAP-MD5
For EAP-MD5 I selected only EAP-MD5
Now if I use a generic rule
DEVICES If Wired_802.1X allowed protocols EAP-PEAP-FAST-MD5
with EAP-PEAP-FAST-MD5 having EAP-PEAP, EAP-FAST, EAP-MD5 selected, it doesn't work
ISE says that there's a protocol mismatch:
"Failure Reason: 12121 Client didn't provide suitable ciphers for anonymous PAC-provisioning"
ISE is trying to authenticate my phone with EAP-FAST while the Cisco phone is useing EAP-MD5
I read in another topic that some of you would consider MAB/Profiling for the APs and probably for the Cisco IP Phones. But I'm wondering if it's possible to have one authentication rule with allowed protocols EAP-PEAP-FAST-MD5
2) Also, if I place the EAP-MD5 authentication rule higher and then have a rule for EAP-PEAP-FAST below it doesn't work because only the first rule is matched. I have configured the first rule with "If authentication fails = Continue"
Does any of you have hints ?

I know now the problem. WLC try to connect with "anonymous bind" to the ldap server. It works well with Win2000. With Win2003 it works only if you open the security. See link: http://support.microsoft.com/kb/320528/en
You haven't the possiblity to configure any username/pwd for a secure ldap query. It's something that is an absolutely need for many customers.
For the moment I will sugest the "workaround" with AP->WLC->Radius->LDAP
Kind regards
