Do we have any documentation? I found the "set password" CLI Guide, but it does not mention allowed characters, maximum length, some of the defaults etc.
I just realized there is a defect in CUC/CUCM 11.5(1) does not support passwords longer than 15 characters
Thanks

"The Administrator login must start with an alphabetic character, be at least six characters long, and can contain alphanumeric characters, hyphens, and underscores. You will need the Administrator login to log in to Cisco Unified Communications Operating System Administration, the command line interface, and the Disaster Recovery System." from https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/11_5_1/cucm_b_installation-guide-cucm-imp-1151/cucm_b_installation-guide-cucm-imp-1151_chapter_0101.html
also, https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/install/11_5_1/cucm_b_installation-guide-cucm-imp-1151/cucm_b_installation-guide-cucm-imp-1151_chapter_010.html has some additional guidelines.

Thanks, Chris!
But again, no mention of a maximum number of characters. I assume it should be something higher than 15 due to the defect I referenced.

There is no limit as far as I know, the bug you are referring to has to do with PCD not necessarily the CUCM, etc. Due to that bug you should not exceed 15 characters until it gets resolved. It's not in any guides as this is a bug and not a limitation.

I realized the Answer File Generator for 11.5 says+enforces the following regarding Administrator and Security Passwords:
"Ensure the password is at least 6 characters long, but no more than 15 characters."
Seems like the defect CSCvb00248 is not limited to PCD (also given the number of TAC SRs).

I'm struggling to find this information as well. In the Installation Guide for CUCM and IM&P 11.5.(1) the section on Password Recommendations has good guidelines but lacks in detail.
Password Recommendations
The installation wizard checks to ensure that you enter a strong password. To create a strong password, follow
these recommendations:
• Mix uppercase and lowercase letters.
• Mix letters and numbers.
• Include special symbols.
• Remember that longer passwords are stronger and more secure than shorter ones.
Similarly, what are the password requirements for the GUI administrator account? Manually changing the GUI admin password sheds a little light.
admin:utils reset_application_ui_administrator_password
New password: *
Confirm new Password: *
Password must be less than 32 characters, run the command again.
