I use linux on my work computers to be able to ssh into servers when their is a problem.

As our business is growing we are looking for software to be able to manage a list of our servers along with their associated usernames and passwords so that we can just open ssh and be logged in at a click. It takes way to long to search for the servers login details within a text file and then open a terminal with ssh and type everything in.

Also is their a linux alternative to active directory for a cpanel based server. I would like all of my support employees to have their own login. This way if one of them quits I can just disable their login instead of resetting all my server passwords

Active dir or LDAP auth would be a long procedure to achieve this. Alternatively,you should just get something like securecrt installed on your client machines and create profiles in that installation for the servers. it saves the passwords and so they don't have to type it in. Just open click the server name and they are in. If they leave, the installation will remain on your client PC so you would have control over it.

What you need is to setup key access so that you can have password-less logins. You can then have each user / staff generate their own public/ private keypair and add their keys to the systems.

To further simplify it, a simple shell script can be scripted to reduce the amount of typing required.
