Re: Can the AP1310 running on IOS 12.3 supporting on LDAP
No. You can configure local authentication on the 1300's, which will allow an AP to act as its own RADIUS server, but it will only authenticate against local user accounts on the AP, not an external LDAP server.
If you were running lightweight mode, the controllers can do "Local EAP" and authenticate to an LDAP, but that's not an option for IOS/autonomous APs.
If you must authenticate against the LDAP with your current deployment, your best option will be to set up a RADIUS server- ACS, IAS, FreeRadius, etc.
Note that there are issues that may come into play when attempting to authenticate using PEAP/MSCHAPv2 against an LDAP directory, so be careful if you're using 802.1X that your inner authentication method is compatible with the directory you're using.
