−
−	~~You need to use your eScience certificate files, and convert them to the PKCS#12 format.~~
−
−	~~If you have them in .pem format, you can use openssl for this.~~
−
−	~~You might have them in the form of the following two files:~~
−	~~~/.globus/usercert.pem~~
−	~~~/.globus/userkey.pem~~
−
−	~~Converted these to the PKCS#12 format with:~~
−	~~openssl pkcs12 -export -in usercert.pem -inkey userkey.pem -out MyCert.p12~~
−
−	'''Note:''' You will first need to unlock your cert with a password you have gave when creating it. Then you need to add a password for the pkcs12 file. Remember this latter password for the later steps!
−

−

−	~~sudo mount /swestore~~
−
−	When asking for a username and password, just press <Enter> (two times). On the third question, you are asked for the password you gave for the pkcs12 file, which you will have to type in, each time you mount this file system.
−
−	~~Done!~~
−
−	~~Now you should be able to browse to the mount point:~~
−	~~cd /swestore~~
−	~~ls -l~~
−
−	~~You chould be able to create files with content, and read the content:~~
−	~~echo "Testing testing 1 2 3 ..." > testfile.txt~~
−	~~cat testfile.txt~~
−
−	~~'''Note''' however, that you are not able to open the file for updating, with editors such as ''nano''.~~
−
−	~~== More Hints ==~~
−	In order to automatically mount the system, you will need to download the server cert and the CA cert via Firefox, and then cat them into a single file, that you place in /etc/davfs2/certs, and then add the filename of it in /etc/davfs2/davfs2.conf like so:
−	~~servercert myservercert.crt~~
−
−	~~(See [http://www.linuxquestions.org/questions/linux-software-2/force-accept-certificates-when-using-mount-davfs-632056/ this link] for more info)~~
−
−	~~Also, you will need to add the user name and password (that you chose when generating the p12 file above) for your client certificate, to /etc/davfs2/secrets (read the help comments about how to do).~~
