Maximum length of User Custom Attributes

Does anybody know the Maximum length of string type user custom attribute?

I cannot find any documents. But tried to find using ISE2.1 Eval OVA. In my testing, it was successful to set 128,000 chars, but it took about 10 minutes  after clicking Save to get response of Web GUI. And I didn't test more than 128,000 chars due too performance concern.

A PM said max length of string type custom attribute is 1800, but more than 1800 chars can be stored as mentioned above. So he asked me to  post question here.

ISE 2.1 seems acting oddly on this. I will log a bug if our team confirms it.

Both ISE 1.4 and 2.0 give "Error: Attribute value exceeded maximum length:4000".

Thanks for reporting it.

I got the following from our dev team.

... In previous versions the length was limited due to the old persistency layer's limitations, in 2.1 we are no longer limited and we can store any custom attribute size, limited only by the DB free space.

Thank you for useful information!!
