Hi there,

LDAP as any other protocol has some limitations, and this is one of them. LDAP doesn't support PEAP Mschapv2, take a look to the compatibility chart below:

Here is one of the documents that metions this compatibility issue just in case you need it:

Let me know if this answers your questions.

Rate if it helps!

Thanks for answers,

Because LDAP doesn't support PEAP Mschapv2, so what can we do if we have acs 5.1 server connect to LDAP and we have user windows 7?

Please give us suggest.

Thx

Peap Mschapv2 only works with Active Directory, if we can change database from LDAP to windows AD then it will be supported. On the ACS 5, you need to select AD1 as a identiy store.

Hi there,

Basically you have 2 options:

1. Connect the ACS 5.x to Active Directory instead of LDAP (AD doesn't have the PEAP limitation.). This will be the easier option as the ACS 5.x - AD integration is pretty straigh forward, you only need the following:

-Domain name

-AD account with role "Account Operator"

-Configure ACS clock and time zone same as your AD servers

2. Change the connection protocol from PEAP to EAP-TLS for example, however this will take a lot more time and work as you will need to create and assign unique certificates for each user. From the chart above you can confirm that EAP-TLS is supported by LDAP.
