11.04 (yes, I probably should upgrade to the next LTS, I guess), suddenly stopped logging in. This was preceded by a pink screen and error in service module redhat a bunch of errors about the harddrive (so they tell me; I wasn't passwd error in service module there. oh, the lives of not IT folk - like living underwater). So now, whenever they logged in through the GUI, nothing happened - click the user, type the password, straight back to login screen. So I ctrl alt F1 to TTY1, and log in, and the only error I got was: http://www.linuxquestions.org/questions/programming-9/pam-authentication-error-saying-error-in-service-module-394760/ "error in service module". Not helpful. Googling that was helpful in that it started to point the blame at PAM, or Pluggable Authentication Modules, which I now know way too much about. But anyway I ended up booting into recovery mode which got me past the login, and then overwriting the /etc/init/tty1.conf to skip login even when not in recovery mode followingthisadvice, which allowed http://creaturefeaturecode.blogspot.com/2012/07/error-in-service-module-ubuntu-pam.html me to access the internet and external drives on the machine. Then I realized that ubuntu logs everything, and I checked /var/log/auth.log, which mentioned a bunch of missing files in /etc/pam.d/ and other fun places. All such fun directories were empty. very strange. So I copied over all of the files from another ubuntu machine into said directories, including a bunch of .so files, and what do you know, login worked. That simple. Moral of the story - read the logs when something goes wrong that you don't understand. Ubuntu writes a lot of logs, and there's a reason for that. I know I made it seem easy here but it probably took 2-3 hours to do all of the above. facepalms: 4 Posted by Leli at 7:47 AM Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest Labels: facepalm, pam, sysadmin, ubuntu No comments: Post a Comment Newer Post Older Post Home Subscribe to: Post Comments (Atom) Followers Blog Archive ► 2015 (5) ► December (1) ► September (1) ► February (3) ► 2014 (2) ► March (1) ► February (1) ► 2013 (4) ► October (2) ► June (1) ► Janua

de facto standard of unified authentication management mechanism in many unices and similar OSes including Solaris, HP-UX, *BSD, MacOSX and Linux. While specifically designed to help PAM module authors to test their modules, that might also be handy for system administrators interested in building a centralised authentication system using common standards such as NIS, SASL and LDAP. Releases The latest release of pamtester is 0.1.2. You can fetch it from here. Installation Just run configure and do the ordinary "make install". Differences between platforms will automatically be handled by the configure script. Let me know if it's not :) Using pamtester Synopsis: pamtester [-v] [-I item=value] [-E var=value] service operation [operation ...] pamtester requires at least three arguments to operate. The first argument is service, which provides the name of the service. The second one is user, which provides the name of the user to handle with PAM. The last one is operation, which specifies the operation for PAM to perform. For example, the following set of arguments pamtester login root open_session instructs the session modules registered to the "login" service to open the session for user "root". Supported operations are listed below: authenticate Authenticate user. A conversation may subsequently take place to prompt user input for necessary authentication information. acct_mgmt Perform account management on user. open_session Open a new session for user. close_session Close the current session for user. chauthtok Change the authentication token currently assigned to user. A conversation may subsequently take place to prompt user input for necessary authentication information. Note that it is probable some operations eventually need additional privileges to fulfill the request, depending on the service configuration. More than one operation may be specified at once. In that case the operations are done in the order of occurrence. Any operation may also be followed by the option flags that are provided between the pair of parenthesis like this: $ pamtester login root "authenticate(PAM_SILENT)" Flags are all named and combinable or inversible with bitwise operators; | (OR), & (AND), ^ (XOR) and ~ (NOT) are accepted. The list of allowed options is shown below: PAM_SILENT PAM_DISALLOW_NULL_AUTHTOK PAM_ESTABLISH_CRED PAM_REINITIALIZE_CRED PAM_REFRESH_CRED PAM_CHANGE_E
