Fix: Ldaperr: DSID-0C0903AA comment: AcceptSecurityContext error data 525 v1772
Summary: A fix for LDAP error 'Ldaperr: DSID-0C0903AA comment: AcceptSecurityContext error data 525 v1772'
Date: Around 2013
Refactor: 16 January 2025: Checked links and formatting.
While tooling around creating this page I came across this very annoying error:
autoyast:~ # ldapsearch -h 10.10.10.101 -D CN=saldap,CN=Users,DC=adldaptest,DC=local -w ******** -b DC=adldaptest,DC=local -x uid=sjoerd
ldap_bind: Invalid credentials (49)
additional info: 80090308: LdapErr: DSID-0C0903AA, comment: AcceptSecurityContext error, data 525, v1772
Turned out that when doing AD LDAP binds like this, you need to use the user principal name (userPrincipalName):
ldapsearch -h 10.10.10.101 -D saldap@adldaptest.local -w ******** -b DC=adldaptest,DC=local uid=sjoerd
Fix: CommVault: Invalid CS Cache
Summary: Fix the situation in which the CommServe cache has become corrupted on a windows client.

I wanted to update a CommVault client and received this error:
It appears that CS cache is corrupt, delete the cache, download updates again and retry.
And when I checked the updates configuration in the commcell console I saw a message confirming that the CommServe Cache was invalid:
The steps to solve this are the following:
- Manually delete the entire directory and recreate the directory
- Login to the CommCell Browser, right-click the CommServe icon, click All Tasks → Download Automatic Updates.
- From the Download Updates Job Options dialog box, click Run Immediately
This will start the download from the updates if you have the updateserver configured. When the downloads are complete you will have a valid CommServe Cache again:
Fix: IIS error: serverruntime@appconcurrentrequestlimit setting is being exceeded
Summary: Fix the IIS error serverruntime@appconcurrentrequestlimit setting is being exceeded

Refactor: 15 December 2024: Checked formatting and added some context.
This error happens on IIS when a IIS server is overloaded. By default, the app pool in which the sites live have limited concurrent requets configured. You need to change three settings as shown below. Don't forget to reboot the server afterwards. This was done and tested successful on a Windows Server 2016 with IIS 10.0
Fix: Editing Excel Documents With Powershell as Scheduled Job Fails
Summary: When automating excel tasks with powershell as a scheduled job you might run into issues, as server-side office tasks are not always that easy. But sometimes the fix is very easy.

Due to some weird issues with excel or powershell (nobody knows for sure although Microsoft claims it's not supported here ) it seems impossible to edit, create or save Excel documents with powershell when running it as a scheduled job, when set that the user running the task does not have to be logged on. Searching the Internet there is a solution, which worked for me and a lot of other people. You'll have to create some folders depending on if you're running Windows in 32bits or 64bits:
You'll always have to create this folder:
C:\Windows\System32\config\systemprofile\Desktop
And if you're running 64bits you also have to create this folder:
C:\Windows\SysWOW64\config\systemprofile\Desktop
Now it will work.
