Lync 2013 Edge : The Buffer supplied to a function was too small [solved]

HI all

Today i cope with a strange behavior on edge server by assigning a public certificat from comodo

By inspecting the log a found this

The cetificat is well imported in the computer certificat container have a private key and the certification path is correct.

By using the following Certutil.exe command i v got this result

C:\Users\Adm-teruin>Certutil.exe -v -store my « 4bf5f126f5011c9dad6b737439f4e0b4 »

To solve this issue

1. Export the certificate with PFX format from the Edge server
   
2. import it on Firefox (my machine was Windows 8.1)
   
3. export it from Firefox with the format P12
   
4. Remove on the edge the assignement on the concerned certificat
   
5. Remove the certificat on the edge server from the certificat store
   
6. import the new formated certificat with the P12 format.
   
7. Assign it to the edge
   

It should works
