[rancid] Unable to pull configuration from Cisco WLC 8.5

You are correct that a lot of my issue was surrounding the logout sequence. Thankfully I was able to get this resolved with the help of John from Rancid. There were two things that were impacting me:
* First, I had an issue with TACACS where the 'config paging disable' could not be executed. To expand on this, there are seven groups to which a user could be assigned on the WLC. It just so happened that I was using the one group, MONITOR, that didn’t allow for the config level command to issues.
* Second, in the process of my troubleshooting I had started to tweak the versions of EXPECT and TCL because of a separate email chain I had read on the discussion board. I had to recently rebuild my server because of a variety of issues. After reinstalling Rancid the WLC scripts now all work correctly.
A couple of things to note that might help people who encounter this issue, some information on install: Centos 7, fully patched, I am running EXPECT version 5.45 and TCL version 8.5. Also I’m running Rancid 3.12.

Do you have the .raw file?
I had this problem at one point too. It had something to do with not correctly parsing the logout sequence. I modified my version to check for the right sequence, but it was an old version of rancid, and my specific logout sequence was caught in a newer version. But, 8.5.161 might have changed the specific text that the logout sequence sends, so rancid’s parser might not catch it yet.

Rancid version: 3.12
Cisco WLC: 220.127.116.11
I cannot successfully pull the configuration from my Cisco WLC. In every case, it just gives the generic error “End of run not found.” However, if I execute the command to pull configuration via rancid, the .new file looks complete and without issue. I have tried changing the various commands executed but with no success. Looking for a smarter person than I to perhaps give some direction or recommendations.
